TCA9538PWR Description

Short technical summary and product information.

The TCA9538PWR from Texas Instruments is an 8-bit general-purpose I/O expander that communicates via the I2C and SMBus protocols. It supports clock frequencies up to 400 kHz and operates within a voltage range of 1.65V to 5.5V. This device is suitable for applications requiring additional I/O pins without consuming significant MCU resources.

 

Key features include an active-low interrupt output and an active-low reset input, providing enhanced control and error handling capabilities. The I/O ports are 5V tolerant, allowing for interfacing with different voltage levels. The TCA9538PWR is available in a 16-TSSOP package, designed for surface mounting.

 

This I/O expander is ideal for expanding microcontroller capabilities in various embedded systems. Its configuration registers allow for flexible input/output direction control, and the polarity inversion register offers further customization. The device also boasts low standby current consumption, making it suitable for power-sensitive applications.
