Description

The PS301/PS302/PS303 are improved high precision, medium

voltage analog switches designed to operate with single power

supplies. The PS301 is a single-pole single-throw (SPST), nor-

mally open (NO) switch. The PS302 has the same pinout as the

PS301 but is a normally closed (NC) switch. The PS303 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, the PS301/PS302/PS303 guarantee

<60Ω ON-resistance. ON-resistance matching between channels

is within 2Ω. ON-resistance flatness is less than 6Ω over the

specified range. All three devices guarantee low leakage currents

(<100pA @ 25oC, <10nA @ +85oC) and fast switching speeds

(tON < 150ns). Break-before-make switching action protects

against momentary crosstalk (PS303).

For single-supply operation below 5V, the PI5A317/318/319

are also recommended.
