The TCA5405 is a 5-bit output expander controlled using a single wire input. This device is ideal for portable applications as it has a wide VCC range of 1.65V to 3.6 V. The TCA5405 uses a self-timed serial data protocol with a single data input driven by a master device synchronized to an internal clock of that device. During a Setup phase, the bit period is sampled, then the TCA5405 generates its own internal clock synchronized to that of the Master device to sample the input over a five-bit-period Data Transfer phase and writes the bit states on the parallel outputs after the last bit is sampled. The TCA5405 is available in an 8-pin 1.5mm × 1.5mm RUG uQFN package.

TCA7408-5405EVM — Evaluation module for TCA7408 and TCA5405
The TCA7408-5405EVM is designed to show the used of multiple TI products on a single evaluation board. It shows how the single-wire 5-bit output expander TCA5405 is used to generate LED blinking functions. The Single wire interface is implemented using a single GPIO port on the MSP430, and very (...)
