DM74ALS27
Triple 3-Input NOR Gate
General Description
This device contains three independent gates, each of
which performs the logic NOR function.
Features
s Switching specifications at 50 pF
s Switching specifications guaranteed over full tempera-
ture and VCC range
s Advanced oxide-isolated, ion-implanted Schottky TTL
process
s Functionally and pin for pin compatible with Schottky
and low power Schottky TTL counterpart
s Improved AC performance over Schottky and low power
Schottky counterparts
