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.
