Description

The PI5A391A/392A are monolithic analog switches designed for low-voltage, single-supply operation. These high-precision devices are ideal for low-distortion audio, video, signal switching and routing applications.

The PI5A391A is a quad single-pole single-throw (SPST), normally closed (NC) switch. The PI5A392A has four normally open (NO) switches.

Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails.
