DM74AS1804
Hex 2-Input NAND Driver
General Description
These devices contain six independent 2-Input drivers
each of which performs the logic NAND function. The
DM74AS1804 is equivalent to the DM74AS804B but the
supply voltage and ground pins are centered in the pack-
age. This positioning of the supply voltage and ground pins
reduce the lead inductance of these pins. This reduction of
lead inductance will minimize noise generated onto either
the supply voltage or ground bus which is significant in high
current switching applications.
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 Centered VCC and GND configuration provides minimum
lead inductance for high current switching applications
s High capacitive drive capability

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device can not 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.
