Products in this family are used primarily to provide informatic connectivity between endpoints that employ differing communication protocols and/or signaling methods. Examples include devices that connect an I2C bus to a UART, USB to I2C, SPI, Ethernet, or UART, Ethernet MACs and PHYs, and others. Also included are devices used to establish multi-way connections using interfaces designed for point-to-point communications, such as USB hub controllers.
