description
These devices contain four independent 2-input
AND buffers/drivers. They perform the Boolean
functions Y = A
B or Y = A+B in positive logic.
The SN54ALS1008A and SN54AS1008A are
characterized for operation over the full military
temperature range of –55
°
C to 125
°
C. The
SN74ALS1008A and SN74AS1008A are charac-
terized for operation from 0
°
C to 70
°
C.
