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 package. 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 temperature 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
