SMBUS I/O Expander 24-Pin BGA MICROSTAR JUNIOR T/R

The TCA6416A is a 24-pin device that provides 16-bits of general purpose parallel input/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 on the I2C bus side (VCCI) and a power supply voltage ranging from 1.65 V to 5.5 V on the P-port side (VCCP). The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. I/O expanders such as the TCA6416A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, etc.
