DESCRIPTION
The CWB2269 is a Precision Dual Single Pole, Double Throw
Analog Switch for precision applications in instrumentation,
communications and process control where low leakage and
high speed switching are required. Designed on the Calogic
CMOS/DMOS process this analog switch takes advantage of
high speed DMOS switching FETs combined with low voltage
CMOS technolo gy in a monolithic stru ctur e.

All devices contain diodes to protect inputs against damage
due to high static voltages or electric fields; however, it is
advised that precaut ion s 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).
