TCA9538 - Low Voltage 8-Bit I2C and SMBus Low-Power I/O Expander
The TCA9538 is a 16-pin device that provides 8 bits of general purpose parallel input and output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol.
The device can operate with a power supply voltage ranging from 1.65 V to 5.5 V.
The device supports both 100-kHz (Standard-mod
