100MHz CMOS/DMOS
Wideband Quad Analog Switch
CORPORATION
CWB201
FEATURES
DESCRIPTION
Designed for RF and Video Switching the CWB201 is
manufactured using Calogic’s high speed CMOS combined
with DMOS transistors in a monolithic design resulting in
superior performance characteristics. This quad SPST switch
array has extensive applications where high frequency video,
audio or digital signals are switched or routed. The CWB201
is TTL compatible which is of great benefit to to designs that
require constant logic switching over a wide range of supply
voltages and temperature without a separate power supply.

NOTE:
All devices contain diodes to protect inputs against
damage due to high static voltages or electric fields;
however, it is advised that precautions be taken not to
exceed the maximum recommended input voltages. All
unused inputs must be connected to an appropriate logic
level (V
DD
or GND).
