DESCRIPTION
The 74V2T384 is an advanced high-speed CMOS
DUAL HIGH SPEED BUS SWITCH fabricated in
silicon gate C
2
MOS technology. It’s designed to
operate from 4.5V to 5.5V, making this device
ideal for portable applications. It’s offers 7Ω
Resistance typical value at V
CC
=4.5V. Additional
key feature are fast switching speed (t
ON
=3.8ns,

and
Low
Power
Consumption.
The OE input is provided to control the switch; the
switch is ON when the OE input is held low and
OFF when OE is held high.
It’s available in the commercial and extended
temperature range in SOT23-8L package.
