Best Answer

Direct coupled transistor logic is a type of transistor that is more economical to use then integrated circuits. These transistors can be found in many types of wires such as the ones that control cable internet.

What is the application of TTL in integrated circuits?

Transistor transistor logic is one type of many different types of bipolar transistor based digital logic circuitry. It is very efficiently implemented in integrated circuit chips, needs only one power supply voltage, and operates at reasonably high speeds. Transistor transistor logic was first developed in the middle 1960s as a modification of the diode transistor logic, then in use in some digital logic integrated circuit chips but dating back to the earliest discrete bipolar transistor logic developed in the late 1950s and derived from vacuum tube point contact diode logic used in many early first generation computers. Transistor transistor logic integrated circuits dominated the computer and electronic digital controller market from the late 1960s until the middle 1980s, when metal oxide semiconductor field effect transistor based microprocessors and microcontrollers began to replace it. By the early 1990s transistor transistor logic and other bipolar transistor based digital logic integrated circuits had been replaced with equivalent complementary metal oxide semiconductor field effect transistor integrated circuits that were both faster and consumed less power (thus running much cooler) or with programmable logic devices of various types. In general transistor transistor logic is now considered obsolete.

How you will compare pass transistor with transmission gate logic?

The use of transmission gates eliminates the undesirable threshold voltage effects which give rise to loss of logic levels in pass transistor logic.

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. 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.ANSWER: ONE WORD SPEED


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.
