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
<30
on-resistance
.
On-resistance matching between channels is
within 2
. On-resistance flatness is less than 4
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 <45
R
ON
, <2
R
ON
match, and <4
R
ON
flatness.
For operation below 5V the PI5A381A/PI5A383A/PI5A385A
are also recommended.
N.C = No Connect.

Notes:
1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in
this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design
4.
R
=
R
max
-
R
min
5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25C.
7. Off Isolation = 20log
10
[ V
COM
/ (V
NO
or V
NO
)
]. See figure 5.
8. Between any two switches. See figure 6.
9. Leakage testing at single-supply is guaranteed by testing with dual supplies.
