Diode and Transistor NAND Gate or DTL NAND Gate and NAND Realizing NAND Gate using Diode and Transistor. For simplicity we will show here only two inputs NAND gate circuit by using diodes and transistors NAND gate is called DTL NAND gate or Diode Transistor Logical NAND Gate. When both input A and B are given with 0 V, both of the diodes are in forward biased condition that is in ON condition. DTL NAND - Falstad This is an NAND gate implemented using diode-transistor logic. Click on the inputs on the left to toggle their state. When all of the inputs are high, the output is low; otherwise, the output is high. When all the inputs are high (3.6 V), the only path to ground through the 4 resistor is through the base of the transistor. So a base current Diode Transistor NAND Gate or DTL NAND Gate - YouTube Click to view on Bing2:24Here we have discussed Diode Transistor NAND Gate or DTL NAND Gate with its details circuit diagram. Here we have discussed Diode Transistor NAND Gate or DTL NAND Gate with its details circuitAuthor: Electrical4UViews: 29K NAND gate - Wikipedia In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate.A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results. A NAND gate is made using transistors and junction diodes.
