Dual 1-Form-A Shunt-Isolated
High-Voltage High-Frequency Analog Switch
Description
The CPC7512 dual 1-Form-A high-voltage,
high-frequency, shunt-isolated analog switch builds
upon IXYS Integrated Circuits Division’s design and
fabrication expertise for industrial applications. This
monolithic solid state device provides the switching
functionality of two normally open (1-Form-A) solid
state relays for high frequency applications in one
small economical package. Both switches incorporate
shunt isolation by means of a T-switch compensation
technique to minimize series capacitance through the
open off-state switches for improved off-state isolation
over frequency.
Designed to provide flexible single-ended or
differential access to high voltage networks, the
CPC7512 is functionally configured as two
independent logical switches. The self-biasing
switches do not require external high-voltage supplies
for proper operation.
An integrated thermal shutdown feature provides not
only enhanced protection for devices connected to
high voltage networks up to +320V, but also an
external signal to indicate the device is shut down.

1.4 General Conditions
CPC7512
Unless otherwise specified, minimum and maximum
values are guaranteed by production testing or design.
Typical values are characteristic of the device at 25°C,
and are the result of engineering evaluations. They are
provided for informational purposes only and are not
guaranteed by production testing.
Unless otherwise noted the specifications cover the
V
DD
operational range and the ambient operating
temperature range T
A
= -40C to +85C. Testing is
performed with the logic low input voltage V
IL
= 0V
DC
and the logic high input voltage V
IH
= V
DD
.
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.
