TCA6408ARGTR 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, operating from a 1.65-V to 5.5-V supply. It supports I2C bus speeds up to 400 kHz (Fast Mode), provides 8 GPIO pins with built-in pull-up resistors, and features an open-drain interrupt output for input change notification. Three address pins allow up to eight devices on the same bus. Packaged in a 16-pin VQFN (RGT) (3 mm × 3 mm), it is ideal 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.
