1962 J. H. Simpson & R. S. Richards Physical Princ. Junction Transistors xvi. 402 Parallel p-n-p inverters form a ‘ not and’ gate, for which all must be one to maintain a zero output.

1987 J. Millman & A. Grabel Microelectronics (ed. 2) vi. 218 This negated and is called a not-and, or a nand, gate.
