DM74AS804B
Hex 2-Input NAND Driver
General Description
These devices contain six independent drivers, each of
which performs the logic NAND function. 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 Functionally and pin for pin compatible with advanced
low power Schottky TTL counterpart

Note 1: The Absolute Maximum Ratingsare 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 Conditionstable will define the conditions
for actual device operation.
