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 mono lithic st ruct ur e.
