CD74HC03E TI High-Speed CMOS Quad 2-Input NAND Gate | 14-PDIP | 2V to 6V, 5ns

Product Overview

The CD74HC03E from Texas Instruments is a high-speed CMOS quad 2-input NAND gate with open-drain outputs. It is part of the 74HC series, offering the high noise immunity and low power consumption of CMOS logic while providing speeds comparable to low-power Schottky TTL (LSTTL). The device operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The open-drain outputs allow wired-AND connections and level shifting, providing design flexibility. Housed in a 14-pin PDIP package, the CD74HC03E is ideal for through-hole PCB designs.
