Description
The PS391/ PS392/ PS393 are improved, quad, single-pole single-
throw (SPST) analog switches designed to operate with 3V to 8V
power supplies or a single 3V to 15V supply. The PS391 has four
normally closed (NC) switches, the PS392 has four normally open
(NO) switches. The PS393 has two NO and two NC switches. All
three devices offer low leakage (<2pA typ) and fast switching
speeds (t
ON
<130ns). Power consumption is less than 1A, ideal for
battery-powered equipment.
With 5V supplies, the PS391/PS392/PS393 guarantee <2ohm
channel-to-channel matching, <30ohm on-resistance (R
ON
), and
<4ohm R
ON
flatness over the specified range.
These switches are fully specified for single +5V operation, with
<2ohm R
ON
match, <45ohm R
ON
, and <4ohm flatness.
For operation below 5V, the PI5A391A/PI5A392A/PI5A393A are
also recommended.

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

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.
