TCA6408AQPWRQ1 TI I/O Expanders
The TCA6408A-Q1 is an automotive-grade, 8-bit remote I2C low-power I/O expander with interrupt output and configuration registers, qualified for AEC-Q100. It operates from a 1.65-V to 5.5-V supply 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, and features an open-drain interrupt output for input change notification. Packaged in a 16-pin TSSOP (PW), it is ideal for expanding GPIO capabilities of microcontrollers in automotive body electronics, portable electronics, and industrial controls.
