Product Details

NXP PCA9554BPWJ — 8-bit I²C-Bus and SMBus I/O Port Expander, 1.65 V to 5.5 V, 400 kHz, TSSOP16, reel of 2583 pieces. Provides eight bidirectional GPIO pins over a two-wire I²C/SMBus interface with open-drain interrupt output, internal 100 kΩ pull-up resistors on all I/Os, and 25 mA sink capability per pin for direct LED driving. Wide supply voltage range from 1.65 V to 5.5 V makes it compatible with modern low-voltage microcontrollers and processors.
