NXP PCA9555APW118 16-bit I/O Expander
The PCA9555APW,118 is a 16-bit GPIO expander with interrupt functionality and weak pull-up resistors suitable for I²C-bus and SMBus applications. It provides additional I/O ports for embedded systems, featuring a flexible I/O configuration with a wide VDD range from 1.65V to 5.5V, enabling compatibility with next-generation microcontrollers and microprocessors operating at lower voltages. The device includes a set of four 8-bit registers for configuration, input, output, and polarity inversion, acting as a pin-compatible replacement for the PCA9555 and similar industry-standard devices. It offers Agile I/O features, an open-drain interrupt (INT) output that signals when an input state changes, and power-up default configurations with all channels set as inputs with weak pull-ups. Designed for low power consumption, the expander features latch outputs capable of driving LEDs with up to 25mA and exhibits robust latch-up performance exceeding 100mA. Its Schmitt-trigger inputs improve switching noise immunity, making it suitable for communications and networking applications. The product currently has extended lead times due to high market demand and is exempt from discounts.
