DM74AS804B Hex 2-Input NAND Driver
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
■Switching specifications at 50 pF
■Switching specifications guaranteed over full tempera-
ture and VCC range
■Advanced oxide-isolated, ion-implanted Schottky TTL
process
■Functionally and pin for pin compatible with advanced
low power Schottky TTL counterpart
Ordering Code:
Devices also available in Tape and R eel. Speci fy by append ing the suffix let t er “X” to the o rdering c ode.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the saf ety of the device cannot be gu aranteed. Th e device shoul d not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “R ecomm ended Oper ating Co ndition s” table will def ine the condit ions
for actu al device operation.
