Single-ended input, multi-terminal output (4 or 5 end) of the NAND gate chip which models?

Is the NAND gate, not the NAND gate! The Thank you! The The Oh, that's how it is!

NAND gate has at least two inputs, where is the single-ended input?

The logic output of the gate is generally only one Such as title TTL level 7402, 7427, 7428, 7433, 7454, MOS level Cc4001, cc4002, cc4013, cc4014, cc4078, cc4501 Learn the door circuit, the combination of the door circuit should be taken
