8.1 Overview
The TS5A3160 is a single-pole-double-throw (SPDT) solid-state analog switch. The TS5A3160, like all analog
switches, is bidirectional. When powered on, each COM pin is connected to the NC pin. For this device, NC
stands for normally closed and NO stands for normally open. If IN is low, COM is connected to NC. If IN is high,
COM is connected to NO.
The TS5A3160 is a make-before-break switch. This means that during switching, a connection is made before
the existing connection is broken. During this brief period, the NC and NO pins are connected to each other.

8.3 Feature Description
The low ON-state resistance, ON-state resistance matching, and charge injection in the TS5A3160 make this
switch an excellent choice for analog signals that require minimal distortion. In addition, the low THD allows
audio signals to be preserved more clearly as they pass through the device.
The 1.65-V to 5.5-V operation allows compatibility with more logic levels, and the bidirectional I/Os can pass
analog signals from 0 V to V₊ with low distortion.
