Introduction

AI Translation

The TCA6408A-Q1 is a 16-pin device that provides 8-bit general-purpose parallel I/O expansion for the two-wire bidirectional I2C bus (or SMBus) protocol. During device operation, both the I2C bus side (Vcci) and the P-port side (Vccp) can be powered by supplies with voltages ranging from 1.65V to 3.6V. This enables the TCA6408A-Q1 to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are being scaled down to conserve power. While microprocessors and microcontrollers operate from reduced supply voltages, certain PCB components (such as LEDs) may still be powered from higher-voltage supplies. The device supports clock frequencies of 100kHz (Standard Mode) and 400kHz (Fast Mode). When additional I/O is required for devices such as switches, sensors, buttons, LEDs, and fans, I/O expanders like the TCA6408A-Q1 provide a simple solution.
