7401 Quad NAND

Quad 2-input positive NAnd gate with open collector output

These devices contain 4 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.

The TI SN5401 & SN54LS01 operate over the full military temperature range of -55°C to 125°C. The SN7401 & SN74LS01 operate over 0°C to 70°C.
