Description and Introduction

Remote 8-Bit I2C and Low-Power I/O Expander with Interrupt Output and Configuration Registers 16-VQFN -40 to 85 The **PCA9534RGVR** from Texas Instruments is an 8-bit I²C-bus and SMBus I/O expander designed to enhance system flexibility by providing additional GPIO ports for microcontrollers and processors. This low-voltage device operates within a 1.65V to 5.5V range, making it suitable for a variety of applications, including industrial controls, consumer electronics, and embedded systems.  

Featuring an interrupt output, the PCA9534RGVR can alert the host controller of input state changes, reducing the need for continuous polling. Its bidirectional I/O pins can be individually configured as inputs or outputs, offering versatility in system design. The device also includes internal pull-up resistors, simplifying circuit implementation.  

With a compact **TSSOP-16** package, the PCA9534RGVR is ideal for space-constrained designs. It supports standard (100 kHz) and fast (400 kHz) I²C communication modes, ensuring compatibility with a wide range of host controllers. Additionally, its low standby current consumption makes it suitable for power-sensitive applications.  

Engineers value the PCA9534RGVR for its ease of integration, robust performance, and reliable operation in diverse environments. Whether expanding I/O capabilities or simplifying system architecture, this component delivers efficient and scalable solutions for modern electronic designs.

Application Scenarios & Design Considerations

Remote 8-Bit I2C and Low-Power I/O Expander with Interrupt Output and Configuration Registers 16-VQFN -40 to 85

Alternative Part Number

  • TCA9534APWR --: Pin-compatible I2C 8-bit I/O expander from TI's TCA series with similar register map and function, drop-in replacement in most designs.
  • PCF8574APWR --: Widely available I2C 8-bit I/O expander with similar functionality; requires minor firmware adjustment but is a common lower-cost alternative.
  • MAX7311AUG+ --: I2C 16-bit I/O expander offering more ports than the PCA9534; suitable when extra I/O is acceptable and a different vendor is preferred.
