TCA6408ARSVR TI I/O Expanders

The TCA6408A is an 8-bit remote I2C low-power I/O expander with interrupt output, configuration registers, and an active-low reset. It operates from 1.65 V to 5.5 V and supports I2C bus speeds up to 400 kHz (Fast Mode). The device provides eight GPIO pins that can be independently configured as inputs or outputs with built-in pull-up resistors. Three address pins allow up to eight devices on the same bus (64 total I/Os). Packaged in a 16-pin VQFN (RSV), it is optimal for expanding GPIO capabilities of microcontrollers. Applications include portable electronics, server management, industrial controls, and automotive body electronics. In stock at HL Electronics – request a quote for fast delivery.
