TCA9543ADR General Description

The unique design of the TCA9543ADR includes pass gates that can be used to limit the maximum voltage passed through the switch. This feature enables seamless communication between devices operating at different voltage levels, eliminating the need for additional protection circuitry. With 5.5-V tolerant I/O terminals and external pull-up resistors, the TCA9543ADR simplifies the integration of devices with varying voltage requirements
