DM74AS1000A Quadruple 2-Input NAND Driver

DM74AS1000A
Quadruple 2-Input NAND Driver

General Description

These devices contain four independent 2-input drivers,
each of which performs the logic NAND function. The
DM74AS1000A is a driver version of the DM 74 AS0 0. Each
driver has increased output drive capability to allow the
driving of high capacitive loads.

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

■ Improved line receiving characteristics

Absolute Maximum Ratings(Note 1)

Note 1: The “Absolute Maximum Ratings” are those values beyond 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.
