TCA6416ARTWR Description

Short technical summary and product information.

The TCA6416ARTWR from Texas Instruments is a 16-bit I2C and SMBus I/O expander designed for voltage-level translation and GPIO expansion. It supports bidirectional voltage-level translation between common voltage rails such as 1.8-V, 2.5-V, 3.3-V, and 5-V.

 

This device operates with a power-supply voltage range of 1.65V to 5.5V and features a maximum clock frequency of 400kHz. It includes essential features like an interrupt output pin, a reset input, and configuration registers, allowing for flexible system design. The I/O ports are 5-V tolerant, enhancing compatibility with various logic levels.

 

Packaged in a 24-WQFN (4x4 mm) or 24-TSSOP, the TCA6416ARTWR is suitable for surface-mount applications. Its low standby current consumption of 3 µA makes it an energy-efficient choice for embedded systems. The expander also offers features like a noise filter on SCL and SDA inputs and latched outputs with high-current drive capability for directly driving LEDs.
