TCA9539RGER Description

Short technical summary and product information.

The Texas Instruments TCA9539RGER is a versatile 16-bit general-purpose parallel input/output (I/O) expander designed for I2C and SMBus applications. It operates across a wide voltage range, from 1.65V to 5.5V, making it suitable for various system designs. The device supports a fast I2C bus frequency of up to 400 kHz.

 

Key features include configuration registers, an interrupt output, and a reset pin, providing flexibility in system control and monitoring. The TCA9539RGER offers 16 I/O pins, each capable of handling currents of 10mA or 25mA. It is designed for surface mount installation and comes in a compact 24-VQFN (4x4 mm) package.

 

This I/O expander is compatible with most microcontrollers and is well-suited for applications requiring additional digital I/O pins without consuming significant microcontroller resources. Its robust design includes features like 5-V tolerant I/O ports and latch-up performance exceeding 100 mA per JESD 78, Class II.
