Description

The NXP PCA9555DB is a 16-bit I/O expander with interrupt output for I2C-bus applications. It's designed for industrial automation, home automation, consumer electronics, automotive applications, smart lighting systems, security systems, IoT devices, and instrumentation and measurement systems. This device features 16 programmable I/O pins, two programmable interrupt pins, internal power-on reset, high-speed I2C interface, programmable polarity inversion, configurable I2C slave address, low standby current consumption, and open-drain active-low interrupt output pin. It's packaged in a 24-SSOP (0.209", 5.30mm Width) and operates at 5V with 5V tolerant input pins. The PCA9555DB is suitable for applications that require a high number of digital inputs/outputs, interrupt generation, and low power consumption. Its compact package and low power consumption make it an ideal choice for space-constrained and battery-powered devices.
