74LS01 IC Quad 2-Input NAND Gate with Open-Collector Output DIP-14 74LS01

Product Overview

The 74LS01 is a digital logic device containing four independent 2-input NAND gates. Unlike standard NAND gates, these feature open-collector outputs, which require an external pull-up resistor to achieve a HIGH logic level. This open-collector structure allows for "wired-AND" connections—where multiple outputs are tied together to perform a logic function—or the ability to drive loads at different voltage levels than the device's supply voltage.
