PCA9534RGVR Description

Short technical summary and product information.

The PCA9534RGVR from Texas Instruments is an 8-bit general-purpose I/O (GPIO) expander designed for I2C and SMBus communication. This device offers a wide operating voltage range of 2.3V to 5.5V, making it suitable for various system designs. It supports a fast 400kHz I2C bus speed and includes an open-drain, active-low interrupt output.

 

Key features include configuration registers for setting I/O direction, a polarity inversion register, and an internal power-on reset. The I/O ports are 5V tolerant, and the device exhibits low standby current consumption of only 1 µA maximum. It is available in a 16-VQFN exposed pad package, suitable for surface mount applications.

 

This I/O expander is ideal for applications requiring additional digital I/Os without consuming significant microcontroller resources. Its robust features, including noise filtering on SCL/SDA inputs and latched outputs with high-current drive capability, make it a versatile component for embedded systems.
