TI TCA5405RUGR

The TCA5405 is a 5-bit output expander with single-wire input control. This device supports a wide VCC range from 1.65 V to 3.6 V, making it an ideal choice for portable applications. The TCA5405 uses a self-timed serial data protocol, providing a single data input driven by the master device. The input is synchronized with the internal clock of the master device. During the setup phase, bit period sampling can be performed. Then, the TCA5405 can generate its own internal clock to synchronize with the internal clock of the master device. As a result, it can not only sample different 5-bit cycle data transmission phases but also write the bit states to the parallel outputs after the last bit sampling is completed. The TCA5405 comes in an 8-pin 1.5 mm × 1.5 mm RUG uQFN package.
