What is meant by wired and logic?
A wired logic connection is a logic gate that implements boolean algebra (logic) using only active and passive components such as diodes and resistors. A wired logic connection can create an AND or an OR gate.
What is TTL AND gate?
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. TTL manufacturers offered a wide range of logic gates, flip-flops, counters, and other circuits. Variations of the original TTL circuit design offered higher speed or lower power dissipation to allow design optimization.
What is a wired or gate?
Answer: To detect a change in two or more signals, an OR gate is usually used. Wired OR is a technique to reduce the number of gates and to use only one signal. If the output signals of the ordinary bipolar circuit and MOS are combined into one, short-circuiting occurs if one of the signals is inverted.
What is wired and logic in CAN protocol?
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 is an example of a transistor logic gate?
What is Transistor-Transistor Logic (TTL)? 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.
What can you do with a wired logic connection?
Open Collector AND gate A wired logic connection is a logic gate that implements boolean algebra (logic) using only active and passive components such as diodes and resistors. A wired logic connection can create an AND or an OR gate. The limitations are the inability to create a NOT gate and the lack of level restoration.
How are bipolar transistors used in logic gates?
In this subsection, we examine how to build logic gates from bipolar transistors, the dominant technology of the 1970s and early 1980s. A bipolar transistor is a three-terminal semiconductor device. Under the control of one of the terminals, called the base, current can flow selectively from the collector terminal to the emitter terminal.
What was the first computer to use transistor logic?
Generally, functions in a single package range from logic gates to a microprocessor. The first PC like Kenbak-1 was used Transistor-Transistor Logic for its CPU as an alternate of a microprocessor. In the year 1970, the Datapoint 2200 was used TTL components and it was the base for the 8008 & after that the x86 instruction set.
