1. General description
The 74HC594; 74HCT594 is an 8-bit serial-in/serial or parallel-out shift register with a
storage register. Separate clock and reset inputs are provided on both shift and storage
registers. The device features a serial input (DS) and a serial output (Q7S) to enable
cascading. Data is shifted on the LOW-to-HIGH transitions of the SHCP input, and the
data in the shift register is transferred to the storage register on a LOW-to-HIGH transition
of the STCP input. If both clocks are connected together, the shift register will always be
one clock pulse ahead of the storage register. A LOW level on one of the two register
reset pins (SHR and STR) will clear the corresponding register. Inputs include clamp
diodes. This enables the use of current limiting resistors to interface inputs to voltages in
excess of VCC.
2. Features and benefits
Synchronous serial input and output
Complies with JEDEC standard No.7A
8-bit parallel output
Shift and storage registers have independent direct clear and clocks
Independent clocks for shift and storage registers
100 MHz (typical)
Input levels:
For 74HC594: CMOS level
For 74HCT594: TTL level
Multiple package options
Specified from 40 Cto+85C and from 40 Cto+125C
3. Applications
Serial-to parallel data conversion
Remote control holding register

16. Legal information
16.1 Data sheet status
[1] Please consult the most recently issued document before initiating or completing a design.
[2] The term ‘short data sheet’ is explained in section “Definitions”.
[3] The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status
information is available on the Internet at URL http://www.nexperia.com.
16.2 Definitions
Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. Nexperia does not give any
representations or warranties as to the accuracy or completeness of
information included herein and shall have no liability for the consequences of
use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local Nexperia sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the Nexperia product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
16.3 Disclaimers
Limited warranty and liability — Information in this document is believed to
be accurate and reliable. However, Nexperia does not give any
representations or warranties, expressed or implied, as to the accuracy or
completeness of such information and shall have no liability for the
consequences of use of such information. Nexperia takes no
responsibility for the content in this document if provided by an information
source outside of Nexperia.
In no event shall Nexperia be liable for any indirect, incidental,
punitive, special or consequential damages (including - without limitation - lost
profits, lost savings, business interruption, costs related to the removal or
replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory.
Notwithstanding any damages that customer might incur for any reason
whatsoever, Nexperia’s aggregate and cumulative liability towards
customer for the products described herein shall be limited in accordance
with the Terms and conditions of commercial sale of Nexperia.
Right to make changes — Nexperia reserves the right to make
changes to information published in this document, including without
limitation specifications and product descriptions, at any time and without
notice. This document supersedes and replaces all information supplied prior
to the publication hereof.
Suitability for use — Nexperia products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of a Nexperia product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. Nexperia and its suppliers accept no liability for
inclusion and/or use of Nexperia products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using Nexperia products, and Nexperia
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the Nexperia
product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
Nexperia does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using Nexperia
products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). Nexperia does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — Nexperia
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nexperia.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. Nexperia hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of Nexperia products by customer.
No offer to sell or license — Nothing in this document may be interpreted or
construed as an offer to sell products that is open for acceptance or the grant,
conveyance or implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
