This document describes the SN54HC03 and SN74HC03 quadruple 2-input positive-NAND gates. These devices have open-drain outputs and require pullup resistors to work correctly. They can be connected to other open-drain outputs to implement active-low wired-OR or active-high wired-AND functions.
The SN54HC03 is a quad 2‑input positive‑NAND gate featuring open‑drain outputs that require external pull‑up resistors. It operates over a military temperature range of –55 °C to 125 °C (SN74HC03: –40 °C to 85 °C) and is available in multiple package options including plastic, ceramic, and DIP.
The document provides absolute maximum ratings, recommended operating conditions, electrical and switching characteristics, as well as important warranty and safety notices for use in non‑critical applications.
