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 technology in a monolithic structure.

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 Vcc or GND).

*(1) Hold input state one setup before LE High to Low
transaction. If Input state Low then Switch ON. If
Input state High then Switch OFF.
