description

These devices contain three independent 3-input

positive-NOR gates. They perform the Boolean

functions Y = A • B • C or Y = A + B + C in positive

logic.

The SN54ALS27A and SN54AS27 are

characterized for operation over the full military

temperature range of –55°C to 125°C. The

SN74ALS27A and SN74AS27 are characterized

for operation from 0°C to 70°C.
