SINGLE FET BUS SWITCH
DESCRIPTION
The U74CBT1G385 features a single high-speed line switch. The
switch is disabled when the output-enable(OE) input is high.
The U74CBT1G385 is characterized for operation from -40°C to
85°C.
FEATURES
* 5-Ω Switch Connection Between Two Ports
* TTL-compatible Control Input Levels
* Packaged in Plastic Small-Outline Transistor Packages
