TTL Logic Circuits - "Transistor Transistor Logic" - are made using BJTs. They operate from +5 Volts. These are available from simple AND, OR, NAND Gates to complex circuits.
The voltage levels are
INPUT OUTPUT
Low (0) < 0.8V <0.4V
High (1) >2.0V >2.4V
Levels in between are undefined. The outputs are better than the inputs by 0.4V thus offering a noise margin. These are seldom used these days as other logic families have been introduced offering more advantages like, speed, lower power, wider / lower operating voltage, higher fanouts.

TTL logic is preferred to DRL logic?
TTL is faster and does not lose amplitude
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.

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.
Which logic family is used to fabricate microprocessor?
TTL
What is TTl in digital electronics?
transistor transistor logic
Whether TTL logic is preferred to DRL logic and why?
DRL cannot invert signals.
Why is a TTL logic gate faster than a CMOS logic gate?
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.
What are the disadvantages of TTL logic family?
Briefly, TTL uses more power than more modern families.
What is full form of TTL used in PIC16f72 micro-controller?
In electronics TTL stands for Transistor Transistor Logic.
What is value of propagation delay of TTL logic?
it is in micro seconds
What are TTL gates?
TTL stand for transistor transistor logic it could be DTL for diode or any other type of family.
