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 ...

Input-A is connected to the drain terminal of MOSFET; Input-B to its gate terminal. The source terminal, labeled as Output-C, is the output of the AND gate. The MOSFET in the circuit ... Figure 2 ...
