What is wired operation?
What is wired operation?
The wired AND connection is a form of AND gate. It uses a pull up resistor and one diode per input to create this function. The positive voltage from the source is directed away from the output C and towards A and B via the diodes connected directed towards the inputs.
What is an open collector input?
An open collector is a common type of output found on many integrated circuits (IC), which behaves like a switch that is either connected to ground or disconnected.
What is a wired or connection?
Glossary Term: Wired-OR It can also be done with a “wired-OR” connection in which two signals are simply wired together and either one of them can raise the level. This works when the signals are driven by a source that only pulls up or only pulls down, with a resistive load (e.g. an “open collector” output).
What is wired AND logic in can?
CAN protocol is based on Wired AND logic. Wired AND logic means – 0 is dominant. Meaning of Zero dominant is that whenever there is a conflict in two data transmissions, then the sender who is sending 0 will get the priority.
Which TTL logic gate is used for wired ANDing?
A universal logic gate is one, which can be used to generate any logic function….

Why open collector output is used?
The advantage of open-collector outputs, or open-drain outputs is that the load to be switched or controlled can be connected to a voltage supply which is independant, and/or different from the supply voltage used by the controlling circuit, and that they can “sink” or “source” an externally-supplied voltage depending …
How does an open-collector circuit work?
An Open Collector output is an NPN transistor. An NPN transistor allows the sinking of current to common. It can be thought of as a switch that allows the circuit, after the load, to be connected to common. This means that a source is required for the output to work.
Which TTL logic gate is used for wired and gate?
What is the most common wired network?
Wired connections are by far the most common. The main media in use are coaxial cable, twisted pairs and fibre optics. For each of these, specific network technologies or specifications have been designed.
What is wired-AND bus?
This applet demonstrates a Wired-AND bus, another common circuit that allows connecting multiple gates to one bus signal. The idea is to use so-called open-collector transistors as the sole connection to the bus. While the output transistor is conducting, the voltage on the bus is actively driven to a low value.
CAN vs CAN FD?
The primary difference between the classical CAN (Controller Area Network) and CAN FD is the Flexible Data (FD). Using CAN FD, Electronic Control Unit (ECU)s can dynamically switch to different data-rate and with larger or smaller message sizes.
Which logic gate is mode using TTL logic?
The Transistor-Transistor Logic (TTL) is a logic family made up of BJTs (bipolar junction transistors). As the name suggests, the transistor performs two functions like logic as well as amplifying. The best examples of TTL are logic gates namely the 7402 NOR Gate & the 7400 NAND gate.
