SN74HC03D TI Logic Gates | 14-SOIC | Quad 2-Input NAND, Open Drain

Product Overview

The SN74HC03D 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 SN74HC00 but with open-drain outputs for wired-AND or level-shifting applications. The 14-SOIC package offers a compact surface-mount solution for space-constrained designs.
