| DM74AS1805 Hex 2-Input NOR Driver DM74AS1805 Hex 2-Input NOR Driver These devices contain six independent 2-Input drivers each of which performs the logic NOR function. The DM74AS1805 is equivalent to the DM74AS805B 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. 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 Ordering Code: Order Number Package Number Package Description DM74AS1805WM M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide DM74AS1805N N20A 20-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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.
