DESCRIPTION
The Calogic CWB308 and CWB309 feature fast switching
(<140ns) and low ON resistance (<40Ω) for excellent
performance in applications in communications, computer
peripherals and instrument controls. This series combines
low power CMOS input logic and level translation circuitry with
high speed, low capacitance DMOS switches in a monolithic
structure.
The CWB308 and CWB309 have CMOS
compatible inputs and also have a standard pin configuration
for second sourcing.

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).
