Texas Instruments’ 5400 and 7400 TTL quad 2-input NAND gate has been in continuous production since 1964 and is the progenitor of what is probably the most numerous breed of integrated circuits, ...

1 Fig. 1 NAND inverting gate and AND non-inverting gate Standard CMOS gates used in IC design are inverting for a variety of reasons, including lower area and delay compared to the non inverting ...
