TECHNICAL DATA

Hex Inverters

with Open-Drain Outputs

KK74LS05

This device contains idenpendent inverts. It performs the Boolean

function Y=A. The open collector outputs require pull-up resistor to

perform correctly. Open-collector devices are often used to generate

higher VOH levels.

Pull-Up Resistor Equations

VCC(Min) - VOH

RMAX=

N1(IOH) + N2(IIH)

VCC(Max) - VOL

RMIN= (IOL + N3(IIL)

Where: N1(IOH)=total maximumoutput high current for all outputs tied to

pull-up resistor

N2(IIH)=total input high current for all inputs tied to pull-up

resistor

N3(IIL)=total input low current for all inputs tied to pull-up

resistor
