TCA9539QPWRQ1 TI I/O Expanders
The TCA9539-Q1 is an automotive-grade, 16-bit remote I2C I/O expander qualified for AEC-Q100, operating from 1.65V to 5.5V. It provides 16 GPIO pins with built-in pull-up resistors, and includes interrupt output and configuration registers. Three address pins allow up to eight devices on the same bus (128 total I/Os). Packaged in a 24-pin TSSOP (PWR), it is ideal for expanding GPIO in automotive body control modules (BCMs), infotainment systems, and lighting control requiring additional I/O lines.
