Abstract: The NAND gate circuit includes at least two input transistors, at least two pull-up modules and at least two input control transistors. A first electrode of each input transistor is connected to a second level output end via the pull-up module. The input control transistor is configured to enable a potential of the control end of the pull-up module connected to the first electrode of the input transistor to be the first level when the input signal connected to the gate electrode of the input control transistor is at a second level. The at least two pull-up modules are configured to cut off the connection between the second level output end and the NAND gate output end when all the input signals are at the second level, and enable the connection therebetween when none of the input signals is at the second level.
