Dual 4-Input Positive-AND GateThese dual 4-input positive-AND Gates SN74LV21A are designed for 2-V to 5.5-V VCC operation.
The 'LV21A devices perform the Boolean function Y = A ? B 1 C ? D or 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. By Texas Instruments |
