Technical content
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 RMAX= RMIN= 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
