Description

The PS381/PS383/PS385 are improved high precision, medium

voltage analog switches designed to operate with +3V to +8V

power supplies.

The PS381 has two normally open (NO) switches. The PS383 is a

dual, single-pole double-throw (SPDT) switch. The PS385 is a

dual, double-pole single-throw (DPST) function. Each switch

conducts current equally well in either direction when on. In the off

state each switch blocks voltages up to the power-supply rails.

With ±5V power supplies, the PS381/PS383/PS385 guarantee

<30Ω on-resistance. On-resistance matching between channels is

within 2Ω. On-resistance flatness is less than 4Ω over the specified

range. All three devices feature low leakage currents (<2 pA @

25oC, <2.5nA @ +85oC) and fast switching speeds (tON<130ns).

Break-before-make switching action protects against momentary

crosstalk (PS383).

These switches are fully specified for single +5V operation,

For operation below 5V the PI5A381A/PI5A383A/PI5A385A

are also recommended.

N.C = No Connect.
