description/ordering information
These dual 4-input positive-AND gates are
designed for 2-V to 5.5-V V_CC operation.
The ’LV21A devices perform the Boolean function
Y + A • B • C • D or Y + A ) B ) C ) D in
positive logic.
These devices are 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 they are powered down.
