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 DM74AS00. Each
driver has increased output drive capability to allow the
driving of high capacitive loads.
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 Improved line receiving characteristics

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
