Overview

The TMUX7212PWR is a high-performance, quad-channel SPST analog switch designed for high-voltage applications up to 44V. It features latch-up immunity and supports bidirectional signal switching with low on-resistance of 2.5 ohms, making it ideal for precision instrumentation and industrial control systems.

Why Choose This Part

The device is latch-up immune, preventing catastrophic failures often caused by parasitic SCR structures in harsh environments. It supports high current up to 220mA and includes fail-safe logic, ensuring the switch remains in a known state during power-up or power-down sequences.

Applications

EV Charging Stations
Used in power modules for signal routing and monitoring in high-voltage environments.
ADAS Sensor Systems
Switching analog signals from automotive sensors while maintaining high signal integrity with -93dB crosstalk.
Automotive Gateways
Managing signal paths between different vehicle subsystems with 1.8V logic compatibility.
Industrial Instrumentation
High-precision data acquisition systems requiring rail-to-rail operation and low leakage current.

Getting Started

Designers should ensure the supply voltage (VDD) is between 4.5V and 44V. Since it is 1.8V logic compatible, it can be interfaced directly with most modern microcontrollers without level shifters. Decoupling capacitors should be placed as close as possible to the VDD pin on the 16-TSSOP footprint.
