| 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.
