DM74S05 Hex Inverter with Open-Collector Outputs
August 1986
Revised April 2000
DM74S05
Hex Inverter with Open-Collector Outputs
General Description
This device contains six independent gates each of which
performs the logic INVERT function. The open-collector
outputs require external pull-up resistors for proper logical
operation.
Pull-Up Resistor Equations
Where:
N
1
(I
OH
)
=
total maximum output high current
for all outputs tied to pull-up resistor
N
2
(I
IH
)
=
total maximum input high current for
all inputs tied to pull-up resistor
N
3
(I
IL
)
=
total maximum input low current for
all inputs tied to pull-up resistor

Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. 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.
