Product Summary
The SN74HC03NSR is a Quadruple 2-input Positive-Nand gate with Open-Drain outputs. The SN74HC03NSR contains four independent 2-input NAND gates. It performs the Boolean function Y= A×B or Y = A + B in positive logic. The open-drain outputs require pullup resistors to perform correctly. The SN74HC03NSR may be connected to other open-drain outputs to implement active-low wired-OR or active-high wired-AND functions.
