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 circuitry with high speed, low capacitance DMOS switches in a monolithic structure. The CWB308 and CWB309 have CMOS compatible inputs and also have a standard pin configuration for second sourcing.

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).
