DESCRIPTION
The 74V1T384 is an advanced high-speed CMOS
SINGLE HIGH SPEED BUS SWITCH fabricated
in silicon gate C
2
MOS technology. It's designed
to operate from 4V to 5.5V, making this device
ideal for portable applications. It's offers 7
Resistance typical value at V
CC
=5V. Additional
key feature are fast switching speed (t
ON
=3.8ns,
t
OFF
=3.3ns Typical) 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 SOT23-5L and SC-70-5L
package.
