MSOP Package Minimizes Board Area
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
@ 25oC, <10nA @ +85oC) 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.
