description/ordering information
These dual 4-input positive-AND gates are
designed for 2-V to 5.5-V VCC operation.
The ’LV21A devices perform the Boolean function
Y
+ A • B • C • Dor Y + A ) B ) C ) D in
positive logic.
These
devices
are
fully
specified
for
partial-power-down applications using Ioff. The Ioff
circuitry
disables
the
outputs,
preventing
damaging current backflow through the devices
when they are powered down.
