Remark

TCA6408AQPWRQ1 General Description

The TCA6408A-Q1 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. This device can operate with a power supply voltage ranging from 1.65 V to 3.6 V on both the I²C bus side (V_CCI) and on the P-port side (V_CCP). This allows the TCA6408A-Q1 to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components such as LEDs remain at a higher power supply.

The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. I/O expanders such as the TCA6408A-Q1 provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and so forth.
