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-

s Advanced oxide-isolated, ion-implanted Schottky TTL

process

lead inductance for high current switching applications

s High capacitive drive capability

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
