3 Description

The TS5A22364 is a bidirectional, 2-channel, single-pole double-throw (SPDT) analog switch designed to operate from 2.3 V to 5.5 V. The device features negative signal capability that allows signals below ground to pass through the switch without distortion. Additionally, the TS5A22364 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/pop noise when switching between two sources. The break-before-make feature prevents signal distortion during the transferring 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 (THD) performance are ideal for audio applications. The 3.00-mm x 3.00-mm DRC package is also available as a nonmagnetic package for medical imaging applications.
