PCA9554PWR Description

Short technical summary and product information.

The Texas Instruments PCA9554PWR is an 8-bit I2C and SMBus compatible I/O expander. It provides a simple solution for increasing the number of available digital I/O pins in embedded systems. The device operates over a wide voltage range of 2.3V to 5.5V, making it suitable for various applications.

 

Key features include 8 configurable I/O pins, a maximum clock frequency of 400 kHz, and an interrupt output pin. The PCA9554PWR supports I²C and SMBus interfaces, allowing for easy integration into existing communication buses. It also includes features like Power-On Reset (POR) and latched outputs with high-current drive capability, suitable for directly driving LEDs.

 

This I/O expander is available in a 16-TSSOP surface mount package, with dimensions of 16-TSSOP (0.173", 4.40mm Width). The operating temperature range is from -40°C to 85°C. Its design facilitates the expansion of I/O ports in microcontrollers and other digital systems where pin count is limited.
