General Description

These devices contain two independent 4-input positive-NAND gates.

They perform the Boolean functions Y = A • B • C • D or Y = A + B + C + D in positive logic.

The SN54ALS20A and SN54AS20 are characterized for operation over the full military temperature range of − 55°C to 125°C.
