Yes, standard 5V powered DTL and TTL devices are fully input/output logic level and fanout compatible. However DTL chips are nearly impossible to find today. The only thing to be careful about is old DTL based designs often used wired-and gates (i.e. directly tying outputs of several gates together to reduce part count). You cannot do this with normal TTL!

What is multi emitter transistor?
A bipolar junction transistor with 2 or more emitters. The most common use of these was in the input section of transistor transistor logic (TTL) gates. They offered significantly higher speed and used less area on the IC chip than the diodes used in the input section of the diode transistor logic (DTL) gates that came earlier. This made TTL ICs both faster and cheaper than the DTL ICs which soon became obsolete.
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.
Whether TTL logic is preferred to DRL logic and why?
DRL cannot invert signals.
What is value of propagation delay of TTL logic?
it is in micro seconds
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
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 are the advantages of TTL over DTL?
because the amplifying function are performed by transistors (contrast with RTL and DTL).
What does transistor to transistor logic mean and what are its uses?
A: TTL-DTL-RTL are family of gates called by the name. Example TTL means Tran. trans. logic. It refers to the inputs for these gates as the type. T= Transistor D=Diode R=Resistor While they do perform the same function their characteristics in performance varies greatly.
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 are the advantages of transistor-transistor logic?
Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.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.

What is ttl circuit?
A digital circuit composed of bipolar junction transistors (BJTs). Widely used in all variety of electronic applications, especially prior to CMOS circuits becoming popular, TTL superseded the earlier RTL (resistor-transistor) and DTL (diode-transistor) logic designs, which used more power. In TTL, transistors are used to both isolate inputs and perform the logic switching. A "TTL" designation on a circuit input or output indicates a digital circuit rather than analog.Read more: transistor-transistor-logic-electronics

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 is meant by standard load in digital electronics?
One standard load is the load of a typical input of a specified logic family. This is more relevant with bipolar logic families (e.g. RTL, DTL, TTL, ECL, I2L) than MOS logic families (e.g. NMOS, CMOS). Outputs of devices in these logic families are then rated by the number of standard loads they can drive. However when crossing between logic families (e.g. LS TTL to S TTL) the concept of standard loads is less useful and actual high/low state input current loading and output drive capability calculations should usually be made.
