TCA6408AQPWRQ1 Description

Short technical summary and product information.

The TCA6408AQPWRQ1 from Texas Instruments is an 8-bit I2C and SMBus compatible IO expander designed for automotive applications. It offers bidirectional voltage-level translation and GPIO expansion between 1.8-, 2.5-, and 3.3-V I2C buses and P-ports.

 

Key features include a configurable I/O level, interrupt output, and reset pin. The device operates over a power-supply voltage range of 1.65V to 3.6V and supports a maximum clock frequency of 400 kHz. It is AEC-Q100 qualified for automotive applications and operates within a temperature grade of -40°C to +125°C.

 

This IO expander is available in a 16-TSSOP package and is suitable for surface mount applications. It provides features like internal power-on reset, noise filters on SCL and SDA inputs, and latched outputs with high-current drive capability for directly driving LEDs.
