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 • 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.

● 2-V to 5.5-V VCC Operation
● Max tpd of 6 ns at 5 V
● Typical VOLP (Output Ground Bounce)
   <0.8 V at VCC = 3.3 V, TA = 25°C
● Typical VOHV (Output VOH Undershoot)
   >2.3 V at VCC = 3.3 V, TA = 25°C
● Ioff Supports Partial-Power-Down Mode
   Operation
● Latch-Up Performance Exceeds 100 mA Per
   JESD 78, Class II
● ESD Protection Exceeds JESD 22
