NANDn.
/nand/, U.S. /nænd/ Computing and Electronics.
A Boolean function of two or more variables that has the value 0 when all of the variables are 1, and otherwise has a value 1; = NOT AND n. Usually attributive.

1958 IRE Trans. Electronic Computers 7 181/3 Using a positive logic (+ is identified with true and one) the circuit represents the binary nor function, A1 + A2 = B. A negative logic (− is identified with true and ONE) results in the binary nand function, A1·A2 = B.

Compounds
NAND gate n. a logic gate that implements the nand function, i.e. whose output signal is 0 when all input signals are 1, and is 1 in any other case.
