DESCRIPTION
The CWB2214 is a High Speed SPST Analog Switch
designed utilizing Calogic's proprietary CMOS/DMOS
processing techniques. The device features low-power
CMOS input logic and level translation circuitry and high
speed, low capacitance lateral DMOS switches fabricated
together in a monolithic structure.

NOTE: 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 (V
DD
or GND).
