TECHNICAL DATA
IN74LS05
Hex Inverters
with Open-Drain Outputs
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
