The onsemi CAT9554AWI-GT2 is an 8-bit I/O expander designed for parallel expansion of I/O ports via a two-wire serial interface. This device supports both I2C and SMBus communication protocols, operating at clock frequencies up to 400 kHz. It features a Power-On Reset (POR) circuit and provides an interrupt output for efficient system signaling. The CAT9554AWI-GT2 offers flexible output drive capabilities, with source current up to 10mA and sink current up to 24mA, utilizing a push-pull output configuration.
This component is housed in a 16-SOIC package, suitable for surface mounting. It operates across a voltage supply range of 2.3V to 5.5V and is rated for an operating temperature range of -40°C to 85°C. The CAT9554AWI-GT2 is commonly deployed in applications requiring expanded digital I/O, such as industrial automation, consumer electronics, and automotive systems. It is supplied in Tape & Reel packaging.
