DM74LS05 Hex Inverters with Open-Collector Outputs
DM74LS05
Hex Inverters 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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “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 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.
