I/O Expanders Texas Instruments PCA9554DGVR Overview
The I/O Expanders Texas Instruments PCA9554DGVR is a versatile, high-performance integrated circuit designed for effective I2C communication. This device enables users to expand eight bi-directional I/O ports, which are configurable as inputs or outputs. Primarily intended for low power applications, the PCA9554DGVR features an interrupt output that can be connected to the interrupt logic of the microcontroller, allowing for prompt response to port changes. Its compact 16-TVSOP package and low power consumption make it an ideal choice for expanding I/O capabilities in embedded systems, while conserving board space and minimizing power overhead.
PCA9554DGVR Features
- 8-bit I/O expander with serial interface
- Compatible with I2C-bus/SMBus interfaces
- Interrupt output for input port change detection
- Low stand-by current consumption
- Operating power supply voltage range of 2.3 V to 5.5 V
- Available in a compact 16-TVSOP package
