DESCRIPTION

The Calogic CWB308 and CWB309 feature fast switching
(<140ns) and low ON resistance (<40Ω) for excellent
performance in applications in communications, computer
peripherals and instrument controls. This series combines
low power CMOS input logic and level translation circ uitr y with
high speed, low capacitance DMOS sw itches in a monolithic
structure. The CWB308 and CWB309 have CMOS
compatible inputs and also have a standard pin configuration
for second sourcing.
