The PS320/PS321/PS322 are improved high-precision, medium voltage 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 <35 ON-resistance. ON-resistance matching between channels is within 2 . ON-resistance flatness is less than 4 over the specified range. All three devices guarantee low leakage currents (<100pA @25, <10nA @+85) 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 recommended.
