Features
Description
PS396A/PS397A low-resistance CMOS analog multiplexers feature
35% lower ON resistance (65-ohm max.) than MAX396/397 devices.
Resistance matching is within 5.5 ohms between switches and resis-
tance flatness is 4-ohms maximum. PS396A is a 16-channel multi-
plexer, and the PS397A is a dual 8-channel differential device.
Application versatility is enhanced through wide supply voltage
operation. Operating voltage options range from dual ±2.7V to ±8V
supplies, to a single +2.7V to +16V supply. With supply current
under 1µA, the devices are ideal for battery powered systems. TTL
logic compatibility exists for dual-supply operation up to ±8V and
for single supply operation under 10V.
Design improvements yield extremely low charge injection (4.5pC
max) and guarantee electrostatic-discharge (ESD) protection greater
than 2000V. They also offer low leakage over temperature (input
off-leakage current less than 1nA at +85°C) and fast switching
speeds (transition time less than 130ns).
The PS396A/PS397A are pin compatible, improved replacements
for the Maxim MAX396/MAX397. Package options include 28-pin
wide SO, DIP and SSOP packages.

Note 1:

CAUTION
Stresses beyond those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This is a
stress only rating and operation of the device at these or any
other conditions beyond those indicated in the operational
sections of this specification is not implied.
Applications Information
Operation with Supply Voltages Other than ±5V
Using supply voltages less than ±5V reduces the analog signal
range. The PS396A/PS397A multiplexers (muxes) operate with ±3V
to ±8V bipolar supplies or with a +3V to +15V single supply. Connect
V to GND when operating with a single supply. Both devices can
also operate with unbalanced supplies, such as +10V and 5V. The
Typical Operating Characteristics graphs show typical on-resis-
tance with ±3V, ±5V, +3V, and +5V supplies. (Switching times
increase by a factor of two or more for operation at 5V or below.)
These muxes operate with a single supply as low as 1V, although on
resistance and switching times become extremely high. Performance
is not guaranteed below 2.7V. This is useful information only
because it assures proper switch state while power supplies ramp up
or down slowly. Overvoltage Protection Proper power-supply se-
quencing is recommended for all CMOS devices. Do not exceed the
absolute maximum ratings, because stresses beyond the listed rat
ings can cause permanent damage to the devices. Always sequence
V+ on first, then V-, followed by the logic inputs, NO, or COM. If
power-supply sequencing is not possible, add two small-signal
diodes (D1, D2) in series with supply pins for overvoltage protection
(Figure 1). Adding diodes reduces the analog-signal range to one
diode drop below V+ and one diode drop above V-, but does not
affect the devices low switch resistance and low leakage character-
istics. Device operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection diodes are not
recommended when using a single supply.
