Texas Instruments PCA9554ADWR is an 8-bit I/O expander featuring an I2C/SMBus interface with a maximum clock frequency of 400 kHz. This device provides 8 bidirectional I/O pins, configurable as inputs or outputs, with individual bit control. It includes a Power-On Reset (POR) feature and an interrupt output for host notification. The PCA9554ADWR supports output sourcing and sinking currents of 10mA and 25mA respectively, with a push-pull output type. Operating within a supply voltage range of 2.3V to 5.5V, it is suitable for applications requiring extended I/O capabilities in industrial automation, consumer electronics, and automotive systems. The component is supplied in a 16-SOIC package, surface mounted, and delivered on tape and reel.
