HD74LV21A
Dual 4-input Positive AND Gates
ADE-205-255 (Z) 1st Edition March 1999 Description
The HD74LV21A performs the Boolean functions Y = A•B•C•D or Y = A+B + C + D in positive logic.
Low-
voltage and high-speed operation is suitable for the battery-powered products (e.
g.
, notebook computers), and the low-power consumption extends the battery life.
