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 are the disadvantages of TTL logic?
TTL logic advantages:-speed of operations -reliability -noise immunity
What are the functions of the TTL logic family?
A: TTL ,RTL or any other family of logic devices have the same functions except these function characteristics are not similar in performance
What are the features of TTL logic family?
Transistor Transistor Logic. Main feature is cheap and old technology. Drawbacks it has limited speed and fan IN-OUT.
Whether TTL logic is preferred to DRL logic and why?
DRL cannot invert signals.
Difrance between ic and ttl?
ic refers to integrated circuits and ttl refers to transistor transistor logic. ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner. integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins
What are the disadvantages of TTL logic?
TTL logic advantages:-speed of operations -reliability -noise immunity
What does TTL applies 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.

Which logic family is used to fabricate microprocessor?
TTL
What are the disadvantages of TTL logic family?
Briefly, TTL uses more power than more modern families.
Ttl logic family has an output state known as?
true and false
TTL logic is preferred to DRL logic?
TTL is faster and does not lose amplitude
What are TTL gates?
TTL stand for transistor transistor logic it could be DTL for diode or any other type of family.
Transfer characterstics of transistor-transistor logic family?
A: The characteristic will be the same as DTL RTL TTL the logic will not change but the transfer function for each family is certainly different
What is meant by ttl logic?
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
What are the features of TTL logic family?
Transistor Transistor Logic. Main feature is cheap and old technology. Drawbacks it has limited speed and fan IN-OUT.
