Automotive SPDT analog switch with negative signalling capability

The Texas Instruments’ TS5A22364-Q1 is a two-channel single-pole double-throw (SPDT) analog switch designed to operate from 2.3V to 5.5V supply. The device features negative signal swing capability that allows signals below ground to pass through the switch without distortion. Additionally, it includes an internal shunt switch, which automatically discharges any capacitance at the NC or NO terminals when they are unconnected to COM. This reduces the audible click-and-pop noise when switching between two sources. The break-before-make feature prevents signal distortion during the transfer of a signal from one path to another. Low On-state resistance, excellent channel-to-channel On-state resistance matching, and minimal total harmonic distortion performance are ideal for automotive infotainment and digital radio applications.
