DM74ALS02 Quad 2-Input NOR Gate

DM74ALS02
Quad 2-Input NOR Gate

General Description

This device contains four independent gates, each of which
performs the logic NOR function.

Features

■ Switching specifications at 50 pF

■ Switching specifications guaranteed over full tempera-

ture and V

CC

range

■ Advanced oxide-isolated, ion-implanted Schottky TTL
process

■ Functionally and pin for pin compatible with Schottky
and low power Schottky TTL counterpart

■ Improved AC performance over Schottky and low power
Schottky counterparts

Absolute Maximum Ratings(Note 1)

Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which

the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
