Product Overview
The SN74HC03N from Texas Instruments is a high-speed CMOS logic device containing four independent 2-input NAND gates with open-drain outputs. Operating from 2V to 6V, it provides the same functionality as the SN74LS03 but with lower power consumption and higher speed. The open-drain outputs allow wired-AND connections and level shifting, making it ideal for bus-oriented systems. Housed in a 14-pin PDIP package, it is suitable for through-hole PCB assembly and prototyping.
