8 Detailed Description

8.1 Overview

The TS5A3157 is a single-pole-double-throw (SPDT) solid-state analog switch. The TS5A3157, 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 TS5A3157 is a break-before-make switch. This means that during switching, a connection is broken before a new connection is established. The NC and NO pins are never connected to each other.

8.3 Feature Description

The low ON-state resistance, ON-state resistance matching, and charge injection in the TS5A3157 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. The control inputs are 5-V tolerant, allowing control signals to be present without VCC.
