U74LV00
QUADRUPLE 2-INPUT
NAND GATE
DESCRIPTION
CMOS IC
The
U74LV00
is designed for 2V to 5.5V V
CC
operation.
The
U74LV00
provides the function
Y=A
B
or
Y=A
B
in
positive logic.
The device is fully specified for partial-power-down applications
using I
off
. The I
off
circuitry disables the outputs, preventing damaging
current backflow through the devices when it is powered down.

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output negative-voltage ratings may be exceeded if the output current ratings are observed.
3. The value is limited to 5.5V maximum.
