DM74LS05 Hex Inverters with Open-Collector Outputs
DM74LS05
Hex Inverters with Open-Collector Outputs
General Description
This device contain s six independe nt gates eac h of which
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: N1 (IOH) = total maximum output high c urrent
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
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 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.
