PCA9534ARGTR Description

Short technical summary and product information.

The PCA9534ARGTR from Texas Instruments is an 8-bit I/O expander that bridges I2C and SMBus interfaces to parallel I/O ports. It is suitable for applications requiring additional digital I/Os without consuming significant microcontroller resources.

 

This device operates within a supply voltage range of 2.3V to 5.5V and supports a fast 400kHz I2C bus speed. It features an open-drain, active-low interrupt output that can signal a microcontroller of incoming data on its ports. The I/O ports are 5V tolerant, providing flexibility in system design.

 

Packaged in a 16-VQFN (3x3) surface-mount package, the PCA9534ARGTR operates across a temperature range of -40°C to 85°C. It offers low standby current consumption, making it suitable for power-sensitive applications. The part includes configuration registers for input/output direction and polarity inversion, along with an internal power-on reset.

 

With three hardware address pins, up to eight PCA9534A devices can be connected on the same I2C/SMBus, or up to 16 when used in conjunction with the PCA9534. This expander is designed for reliable operation, with ESD protection exceeding JESD 22 standards and latch-up performance exceeding 100 mA.
