description
These devices contain four independent 2-input
NAND buffers/drivers. They perform the Boolean
functions Y = A•B or Y = A+B in positive logic.
The SN54ALS1000A and SN54AS1000A are
characterized for operation over the full military
temperature range of – 55°C to 125°C. The
SN74ALS1000A and SN74AS1000A are charac-
terized for operation from 0°C to 70°C.
