CMOS/DMOS

Quad Monolithic SPST

Wide Band Analog Switches

CWB308 / CWB309

FEATURES

APPLICATIONS

DESCRIPTION

The Calogic CWB308 and CWB309 feature fast switching

(<140ns) and low ON resistance (<40

Ω) 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
