Descriptions:

The XRA1201 is a low-voltage, 16-bit I/O expander designed for I²C/SMBus applications. It provides general-purpose remote I/O expansion for microcontrollers, allowing bidirectional data transfer. The device features interrupt capability, reducing the need for polling.

Features:

• 16 Programmable I/O Pins: Each pin can be independently configured as input or output.
• Low Standby Current: Optimized for power-sensitive applications.
• Internal Power-On Reset (POR): Ensures reliable startup.
• Schmitt Trigger Inputs: Improved noise immunity.
• Address Selection: Three address pins allow up to eight devices on the same bus.
• Industrial Temperature Range: Suitable for harsh environments.
• RoHS Compliant: Lead-free and halogen-free.

This device is commonly used in industrial control, networking, and consumer electronics for expanding I/O capabilities.
