DESCRIPTION
The CWB5341 is a Dual Monolithic Analog Switch. Designed
utilizing "T" switching techniques this device gives
exceptionally low crosstalk and very high OFF isolation. The
CWB5341 is built on the Calogic proprietary CMOS/DMOS
process to achieve TTL compatibility with ultra low
capacitance and superior switching performance.

FUNCTION DIAGRAM
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 V
cc
or GND).
