Description

The PS323/PS324/PS325 are improved high-precision, medium voltage analog switches designed to operate with single power supplies. The PS323 is a dual, single-pole single-throw (SPST), normally open (NO) switch. The PS324 has the same pinout as the PS323 but it has two normally closed (NC) switches. The PS325 has one normally open (NO) and one normally closed (NC) switch per package. Each switch conducts current equally well in either direction when on. In the off state, each switch blocks voltages up to the power-supply rail.
