Frequently asked questions
What is the difference between SN7401N and SN7400N?
The SN7401N has open-collector outputs, while the SN7400N has totem-pole (push-pull) outputs. The open-collector output allows wired-AND connections and higher voltage pull-up, but requires an external pull-up resistor for a logic high level.
What is the equivalent of SN7401N?
A functional equivalent is the 4030BDM, also a quad 2-input NAND gate, but it is a CMOS part (4000 series) with different voltage levels and pinout. Verify compatibility with your circuit before substituting.
