Quad High Voltage Isolated
Analog Switch Array
Description
The CPC7524 Quad High Voltage (HV) isolated
Analog Switch Array builds upon our high voltage
design and fabrication expertise for offline and
telecom applications. This monolithic solid state
device provides the switching functionality of four
normally open (1-Form-A) relays in one small
economical package.
Designed to provide flexible single-ended or
differential access to high voltage networks, the
CPC7524 high voltage array is configured as two sets
of matched paired switches for improved differential
performance. Additionally, sensitive differential
applications will benefit from the matched pairs’
excellent pair-to-pair isolation. The self-biasing
switches do not require external high-voltage supplies
for proper operation.
Independent switch current limiting and switch-pair
thermal shutdown features provide enhanced
protection for devices connected to high voltage
networks up to +600V.

1.4 General Conditions
CPC7524
Unless otherwise specified, minimum and maximum
values are guaranteed by production testing. Typical
values are characteristic of the device and are the
result of engineering evaluations. They are provided
for informational purposes only and are not
guaranteed by production testing.
Specifications cover the operating temperature range
T
A
= -40C to +85C. Also, unless otherwise specified,
all testing is performed with V
DD
= 3.3V
DC
, logic low
input voltage is 0V
DC
and logic high input voltage is
3.3V
DC
.
Absolute maximum electrical ratings are at 25C.
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
data sheet is not implied.
