Texas Instruments TMUX28x CMOS Multiplexers

Introduction

The Texas Instruments TMUX28x CMOS Multiplexers are versatile semiconductor devices designed to efficiently manage signal routing in various applications. With their robust features and configurations, these multiplexers are ideal for both analog and digital signal processing.

Part Description

The TMUX28x series is available in two configurations: a 1:1 2-channel and a 2:1 1-channel setup. They support a high current of up to 1.1A and offer bidirectional powered-off protection up to ±5.5V, ensuring reliable operation even when no supply voltage is present. These multiplexers can handle a supply voltage range of 1.8V to 5.5V while being capable of passing signals beyond the supply range from -5.5V to 5.5V. With ultra-low on-resistance of 0.16Ω and a low total harmonic distortion plus noise (THD+N) of just 0.001%, the TMUX28x is an excellent choice for applications requiring precision signal integrity.
