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,
with <45Ω RON, <2Ω RON match, and <4Ω R

For operation below 5V the PI5A381A/PI5A383A/PI5A385A
are also recommended.
