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 func tion. Each driver h as
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 V
CC
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 availab le in Tape and Reel. Specify by appending th e s uffix let t er “X” to the ordering code.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limit s. The parametric values defin ed in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recomme nded O peratin g Cond itions ” table will defin e the condition s
for actual device operation.
