HD74LV21A
Dual 4-input Positive AND Gates
ADE-205-255 (Z)
1st Edition
March 1999
Description
The HD74LV21A performs the Boolean functions Y = ABCD 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.
