| 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 PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs A L H Output Y H L PIN 14 =VCC PIN 7 = GND 1 IN74LS05 MAXIMUM RATINGS* Symbol VCC VIN VOUT Tstg * Parameter Supply Voltage Input Voltage Output Voltage Storage Temperature Range Value 7.0 7.0 7.0 -65 to +150 Unit V V V C Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.
