DM74ALS05A Hex Inverter with Open Collector Outputs
DM74ALS05A
Hex Inverter with Open Collector Outputs
General Description
This device contain s six i ndepe ndent gates, each o f whi ch
performs the logic INVERT function. The open-collector
outputs require exter nal pull-up r esistors for pr oper logical
operation.
Pull-Up Resistor Equations
Where: N
1
(IOH) = total maximum output HIGH current
for all outputs tied to pull-up resistor
N
2
(IIH) = total maximum input HIGH current
for all inputs tied to pull-up resistor
N
3
(IIL) = total maximum input LOW current for
all inputs tied to pull-up resistor
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 Schottky
and low power Schottky TTL counterpart
■ Improved AC performance over Schottky and low power
Schottky counterparts

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
