description
These devices contain two independent 4-input
AND gates. They perform the Boolean functions
Y = A
B
C
D or Y = A + B + C + D in positive
logic.
The SN54F21 is characterized for operation over
the full military temperature range of –55
°
C to
125
°
C. The SN74F21 is characterized for
operation from 0
°
C to 70
°
C.
