pca9531pw

The PCA9531PW is a versatile and highly efficient 8-bit I2C-bus I/O port with interrupt and reset. This product is ideal for various applications, including Industrial Automation, Consumer Electronics, and Computing, and provides 8 bits of General Purpose Parallel Input/Output (GPIO) expansion for I2C-bus (SMBus I2C) and enables you to connect multiple devices to a single I2C-bus. The PCA9531PW features a low standby current, 5V I/O compatibility, and a 400 kHz fast mode I2C-bus interface. It also supports 5V backplane applications. The device has a hardware address pin, accommodating up to 4 devices on the I2C-bus without additional external components. With its interrupt output feature, it can be used in applications requiring an output to signal when input changes. Additionally, the device has an active LOW interrupt output, which is open-drain and can be wire-ORed with other open-drain outputs. With its versatile features and ease of use, the PCA9531PW is an excellent choice for adding I/O ports to your application.
