Description
ThePS320/PS321/PS322areimprovedhigh-precision,mediumvolt-
age analog switches designed to operate with ±3V to ±8V power
supplies. The PS320 is a dual, single-pole single-throw (SPST),
normally open (NO) switch. The PS321 has the same pinout as the
PS320 but it has two normally closed (NC) switches. The PS322 has
one normally open (NO) and one normally closed (NC) switch per
package. When on, each switch conducts current equally well in
either direction. In the off state, each switch blocks voltages up to
the power-supply rails.
With ±5V power supplies, the PS320/PS321/PS322 guarantee
<35ohmON-resistance.ON-resistancematchingbetweenchannels
is within 2ohm. ON-resistance flatness is less than 4ohm over the
specified range. All three devices guarantee low leakage currents
(<100pA @25°C, <10nA @+85°C) and fast switching speeds (tON
<150ns). Break-before-make switching action protects against
momentary crosstalk (PS322).
For single-supply operation the PS323/PS324/PS325 are recom-
mended.
