Package information : DIP 14 Pin Type

Manufacturer : Texas Instruments, Fairchild, National Semiconductor


7401 NAND Gate


This 7401 device contains four independent gates each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation.

These devices contain four independent 2-input NAND gates. The open-collector outputs require pull-up resistors to perform correctly. They may be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions. Open-collector devices are often used to generate higher Voh levels.
