PCA9534APWR General Description

The PCA9534APWR is a 8-bit I2C and SMBus I/O expander with interrupt output and configurable internal oscillator. It has 8 high-drive (25mA) and 8 low-drive (5mA) open-drain I/O pins that can be used to expand the I/O capabilities of a microcontroller or other device.The device features a programmable interrupt output that can be configured to trigger in various conditions such as when input pins change state or when certain conditions are met. It also has programmable I2C slave addresses to allow multiple devices to be connected on the same bus.The PCA9534APWR has a wide operating voltage range from 2.3V to 5.5V and is available in a small 16-pin TSSOP package. It is suitable for various applications such as LED dimming, push button inputs, PWM generator outputs, and sensor inputs.
