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 ver y fast DMO S sw itching FETs.

FUNCTION DIAGRAM

All devices contain diodes to protect inputs against damage
due to high static voltages or electric fields; however, it is
advised th a t p re cau ti o ns be ta ken no t to exceed the maximum
recommended input voltages. All unused inputs must be
connected to an appro pri ate logic level (eit he r V

cc

or GND).
