The TXE8124-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 TXE8124-Q1 supports both standard point-to-point communication along with daisy-chaining of multiple devices.
The device supports 10MHz from 3.3V to 5.5V and 5MHz from 1.65V to 5.5V. I/O expanders, such as the TXE8124-Q1, are designed for when additional I/Os are needed for switches, sensors, push-buttons, LEDs, and fans.
The TXE8124-Q1 devices has 3 I/O ports of 8 IOs each, which include additional features designed to enhance the I/O performance in terms of speed, power consumption, and flexibility. These include per I/O programmable open-drain or push-pull outputs, programmable pull-up and pull-down resistors, bus-hold latchable inputs, maskable interrupt, interrupt status register, glitch filter and a fail-safe register mode which is enabled by the FAIL-SAFE pin.
