TCA9539PWR Description

Short technical summary and product information.

The TCA9539PWR from Texas Instruments is a 16-bit general-purpose parallel input/output (I/O) expander designed for I2C and SMBus interfaces. It operates over a voltage range of 1.65V to 5.5V and supports a maximum clock frequency of 400 kHz.

 

Key features include 16 I/O pins, an interrupt output, and a Power-On Reset (POR) function. The device is available in a 24-TSSOP package, suitable for surface mount applications. It offers current capabilities of 10mA and 25mA and operates within an industrial temperature range of -40°C to 85°C.

 

This IO expander is compatible with most microcontrollers and provides a flexible solution for increasing the number of available I/O pins in embedded systems. Its design includes features like polarity inversion registers and latched outputs with high-current drive capability.
