Thus, a supply of 25-35V is a good choice to generate the square wave signal applied to the two ends of the test wire. Figure 2 Schematic diagram of wire break detector using CMOS memory cell (shown ...

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 ...

The first circuit to be created is 'Invert', that is, a circuit that outputs '0' for the input of '1' and '1' for the input of '0'. The NAND gate is a circuit that outputs '0' when both inputs are ...

A NAND gate can of course be realized by adding M2 and R3 to form an output inverter. Figure 3 Two-input NAND gate (a), and MOSFET realization (b) For a more analog MOSFET application, consider this ...

Therefore, by forcing input B to a logic low, Q2 is always closed and Q6 is always opened, and you can use A as input 1 and C as input 2, with the gate working as a two-input CMOS NAND gate.
