The main limitation on the use of Emitter Coupled Logic is that it is very very power hungry, so the devices tend to require a significant cooling system to remove the waste heat. But in most systems where the speed advantage offered by Emitter Coupled Logic is deemed a necessary requirement, this is usually considered a minor price to pay.

What is fastest logic family from ecl and cmos?
ecl
Which logic family has lowest power dissipation?
cmos
What is voltage level for a negative logic system?
could be negative or positive"negative logic" just means, that the level used by "positive logic" within that logic family for False, is instead used for "True" and vice versa.
What is TTL logic family?
To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster. TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed. = In TTL (Transistor-Transistor Logic), think that the device using this technology is made from several transistors. Another advantage is that many more chips employ this technology.
What is business logic and presentation logic in java?
business logic ....refers to the domain specific logic rules,proc,and processes presentation logic......concerned with how objects are displayed to the user of the software
What is fastest logic family from ecl and cmos?
ecl
What is the fastest logic family?
ECL is the fastest logic family.
RTL ECL HTL HCL in what logic is the fastest?
ECL
How does emitter coupled logic works?
In electronics, emitter-coupled logic, or ECL, is a logic family in which current is steered through bipolar transistors to prevent saturation.
Why ECL is faster than TTL in digital electronics?
Because in ECL logic Transistors doesn't go to saturation region hence saving the recovery time and making this family the faster.
Why ECL family is fastest?
ECL or emitter coupled logic is faster than TTL type logic because the switching transistors do NOT go into saturation in either the on or off state. The switching time from saturation in a high output to saturation in a low state like TTL requires that the junction capacitance be overcome and that the charge in the saturated junction get swept out. ECL is sensitive to a threshold level only.
Which logic circuit is low energy logic circuit ECL OR TTL?
I believe you mean low power, not low energy.TTL is typically lower power than ECL, but not always. Some TTL devices have been higher power than similar ECL devices.
Can you give me a sentence using the word flaw?
The flaw was shaped like a pink panther. He was unable to see the flaw in his own logic. The flaw escaped the inspector's notice.
What does applying mean?
TTL is a logic family. A logic family is the set of logic gates designed using a specific approach. Or simply speaking, logic family is the way of implementing logic. TTL stands for transistor - transistor - logic. It involves transistors (BJT) to implement logic. TTL applies means TTL logic family is used or can be applied in that specific application.

The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
What is logic family in digital electronics?
Transistor Transistor Logic. Main feature is cheap and old technology. Drawbacks it has limited speed and fan IN-OUT.
