Nxp (2428177) I/O Expander, 8bit, 400 kHz, I2C, 1.65 V, 5.5 V, TSSOP

Product Overview
The PCAL9554BPWJ is an 8-bit general purpose Input/output (GPIO) Expander with interrupt and weak pull-up for I²C-bus/SMBus applications. The NXP I/O expander provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. In addition to providing a flexible set of GPIOs, the wide VDD range of 1.65 to 5.5V allows the expander to interface with next-generation microprocessors and microcontrollers where supply levels are dropping down to conserve power. It contains the PCA9554A register set of four 8-bit configuration, input, output and polarity inversion registers and additionally, the expander has Agile I/O, which are additional features specifically designed to enhance the I/O. The additional features includes programmable output drive strength, latchable inputs, programmable pull-up/pull-down resistors, maskable interrupt, interrupt status register, programmable open-drain or push-pull outputs.
