•
Narrow SOIC and DIP Packages Minimize Board Area
PS4530A/PS4531A/PS4532A are low voltage CMOS analog ICs
configured as an 8-channel multiplexer (mux) (PS4530A), two
4-channel muxes (PS4531A), and three single-pole/double-throw
switches (PS4532A). These devices are pin compatible with the
industry standard 74H4351/74HC4352/74HC4353. All devices have
two complementary switch-enable inputs and address latching.
The PS4530A/PS4531A/PS4532A operate from a single supply of
+2V to +12V, or from dual supplies of ±2V to ±6V. On-resistance
(65Ohm max.) is matched between switches to 2Ohm max. Each
switch can handle rail-to-rail analog signals. Off-leakage current is
only 1nA at T
A
= +25°C and 50nA at T
A
= +85
o
C.
All digital inputs have 0.8V and 2.4V logic thresholds, ensuring
both TTL-logic and CMOS-logic compatibility when using ±5V or
a single +5V supply.

device. This is a stress rating only and functional
operation of the device at these or any other con-
