Diode Logic Gates

How to build a diode or gate circuit.

Diode logic gates. Some logic gates can be produced with just diodes and resistors called diode resistor logic or drl. The two basic logic circuits are the and gate and the or gate. Nor diode transistor logic dtl gate.

In this instructable we will build drl circuits. Diode logic or gate wired or connection if one or both inputs are at logic 1 5 volts the current will flow through one or both diodes. An or gate immediately followed by a not gate constitutes the or not or nor gate.

It is seen that the diode anodes are connected to a 5 v supply v cc via resistor r 1. Forward and reverse bias switch a diode between the low and high impedance states respectivelyso that it may serve as. Diode resistor logicdiodes can perform switching and digital logic operations.

In this project we will show how to build an or gate circuit with diodes. Diode logic was used extensively in the construction of early computers where semiconductor diodes could replace bulky and costly active vacuum tube elements. An or gate is a logic circuit that turns on an output if one of the inputs is high or a logic state of 1.

Figure 3 49 shows the circuit diagram of a diode and gate. Diode logic dl or diode resistor logic drl is the construction of boolean logic gates from diodes. A diode logic circuits produces an output voltage which is either high or low depending upon the levels of several input voltages.

This current passes through the resistor and causes the appearance of a voltage across its terminals thereby obtaining logic 1 on the output.
