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.

With a +5V power supply, PS323/PS324/PS325 guarantee <60-ohm ON-resistance. ON-resistance matching between channels is within 2W.  ON-resistance flatness is less than 6W over the specified range. All three devices guarantee low leakage currents (<100 pA @ 25, <10nA @ +85) and fast switching speeds (tON <150ns). Break-before-make switching action protects against momentary crosstalk (PS325).

For single-supply operation below 5V, PI5A317/318/319 are also recommended.
