Dout Data Output Display serial output. Can be used to connect to Din of the next SMARTSWITCH. As a result,
many SMARTSWITCHES can be controlled with one clock and data signal.
FLM First Line Marker The marking signal for the first line data of LCD display. The first line of LCD will be selected
by the falling edge of LP signal during the high level (FLM).
LP Latch Pulse Line data latch pulse will latch content of internal 40-bit shift register at falling edge for one
line of display. LP will also increment the display line by one.
SCP Serial Clock Pulse Clock used by 40-bit internal shift register of the switch, shifting the display data bit presented
at Din at falling edge.
Din Data Input Display serial data bit. Note: to map the display data, because of the difference between the
number of internal shift register data (40) and the single line of LCD pixels (36), the first four
bits of data shifted will be dummy bits.
GND Ground
VDD Power Power source for logic circuit
VLC Power Power source for LCD drive

PRECAUTIONS FOR HANDLING & STORAGE
Handling
1. The VLC voltage should not be applied before logic voltage. If VLC voltage is present before logic voltage, it may cause the driver
logic to freeze and damage the LCD, and the driver logic itself may become damaged.
2. The IS Series devices are electrostatic sensitive.
3. Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage LCD device.
4. Recommended soldering time and temperature limits are 5 seconds maximum @ 270°C maximum.
5. Do not exceed 60°C at the LCD level.
6. The IS series devices are not process sealed.
7. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or clothing.
8. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry with
clean cloth. Do not use organic solvent.
Storage
1. Store away from direct sunlight.
2. Keep away from static electricity.
3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
Terminal numbers are
not on the switch.
