Overview
The NLAS54405MT2TBG, produced by onsemi, is a single supply, bidirectional, dual single-pole/double-throw (SPDT) ultra-low distortion, high OFF-isolation analog switch. This component is designed to operate from either a 3.3 V or 5 V single supply and is primarily targeted at consumer and professional audio switching applications, such as computer sound cards and home theater products. It can handle ground-referenced analog signals up to 2 V RMS and features special circuitry to eliminate clicks and pops during power-up, power-down, and switching operations.
