The TXE81xx-Q1 devices provide general purpose parallel input/output (I/O) expansion for the four wire Serial Peripheral Interface (SPI) protocol and is designed for 1.65V to 5.5V VCC operation.

The device supports 10MHz from 3.3V to 5.5V and 5MHz from 1.65V to 5.5V. I/O expanders such as the TXE81xx-Q1 provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and so on.

The TXE81xx-Q1 devices have I/O ports which include additional features designed to enhance the I/O performance in terms of speed, power consumption and EMI. The additional features are: programmable pull-up and pull-down resistors, latchable inputs, maskable interrupt, interrupt status register, programmable open-drain or push-pull outputs and a fail-safe register mode in situations of watchdog events.
