Overview

The TMUX5412PWR is a high-voltage, 4-channel, single-pole single-throw (SPST) analog switch designed to operate with single-supply voltages up to 50V or dual supplies up to +/-25V. It offers 21 Ohm typical on-resistance and is 1.8V logic compatible, making it suitable for interfacing between high-voltage analog signals and low-voltage digital controllers.

Why Choose This Part

This switch provides a massive 50V operating range while maintaining a low 13pC charge injection and 26 Ohm maximum on-resistance. Its rail-to-rail bidirectional operation and ultra-low leakage current (25uA standby) ensure high signal integrity across diverse power configurations.

Applications

Data Acquisition Systems
Used for signal routing and multiplexing in systems requiring high dynamic range and high-voltage signal handling.
Industrial Instrumentation
Ideal for switching sensor inputs or control signals in 24V or 48V industrial environments.
Test and Measurement
Effective in automated test equipment (ATE) for signal conditioning and routing with its 400MHz bandwidth.
Factory Automation
Reliable switching for high-voltage logic and analog signals in programmable logic controllers (PLCs).

Getting Started

When designing with the TMUX5412PWR, ensure that decoupling capacitors are placed close to the VDD and VSS pins, especially in high-speed switching applications. Since the logic pins are 1.8V compatible, no level shifting is required when interfacing with modern low-voltage MCUs or FPGAs.
