DESCRIPTION
The CWB4500 is a very high performance Monolithic 4 Channel
Wideband/Video Multiplexer designed for switching wide
bandwidth analog and digital signals. The high speed, low ON
resistance and low capacitance is achieved through Calogic’s
proprietary CMOS/DMOS process that combines low-power
CMOS control logic with very fast DMOS switching FETs.

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 (either Vcc or GND).
