DESCRIPTIONThe 74V1G384 is an advanced high-speed CMOS
SINGLE HIGH SPEED BUS SWITCH fabricated
in silicon gate C2 MOS technology. It’s designed
to operate from 3V to 5.5V, making this device
ideal for portable applications. It’s offers 7Ω
Resistance typical value at VCC=4.5V. Additional
key feature are fast switching speed (tON=3.8ns,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.

CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
