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.
