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

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

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.
