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) ORDERING INFORMATION IN74LS05N Plastic IN74LS05D SOIC TA = -0° to 70° C for all packages
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
