NXP USA Inc. PCA9554ATS-112 is an 8-bit I/O expander designed for systems utilizing I2C and SMBus interfaces, operating at up to 400 kHz. This device features a Power-On Reset (POR) circuit and provides eight push-pull I/O pins with configurable output drive capabilities (10mA source, 25mA sink). The expander supports interrupt output functionality for efficient event notification. It is supplied in a 20-SSOP package, suitable for surface mounting. The PCA9554ATS-112 is commonly employed in automotive, industrial automation, and consumer electronics applications where expanded I/O is required without significant microcontroller resource allocation. It operates within a voltage supply range of 2.3V to 5.5V and is rated for an operating temperature of -40°C to 85°C.
