M74HC03B1R ST Quad 2-Input NAND Gate | 14-DIP | 2V-6V, High-Speed CMOS

Product Overview

The M74HC03B1R is a high-speed CMOS quad 2-input NAND gate with open-drain outputs, manufactured by STMicroelectronics. It is part of the 74HC series, offering the same pin configuration as the LS-TTL counterpart but with lower power consumption and higher noise immunity. The device operates over a wide voltage range from 2V to 6V, making it suitable for battery-powered applications. The open-drain outputs allow wired-AND connections and level shifting. Packaged in a 14-pin DIP, it is ideal for through-hole PCB designs.
