What are the types of logic families?

What are the types of logic families?

Types of Logic Family

  • Diode logic (DL)
  • Resistor Transistor Logic (RTL)
  • Diode Transistor Logic (DTL)
  • Integrated Injection Logic (IIL or I2L)
  • Transistor Transistor Logic (TTL)

What is the CMOS logic family?

CMOS (complementary metal-oxide-semiconductor) technology is used predominantly to create digital circuitry. The fundamental building blocks of CMOS circuits are P-type and N-type MOSFET transistors. CMOS technology employs two types of transistor: n-channel and p-channel. …

What is TTL logic family and CMOS family?

The types of logic devices are classified in “families”, of which the most important are TTL and CMOS. The main families are: TTL (Transistor-Transistor Logic), made of bipolar transistors. CMOS (Complementary Metal Oxide Semiconductor) made from MOSFETs. ECL (Emitter Coupled Logic) for extremely high speeds.

What is logic family state different types of logic families?


  • Resistor–transistor logic (RTL)
  • Diode–transistor logic (DTL)
  • PMOS and NMOS logic.
  • Emitter-coupled logic (ECL)
  • Transistor–transistor logic (TTL)
  • Complementary MOS (CMOS) logic.
  • Bipolar CMOS (BiCMOS) logic.
  • What is digital logic family give the classification of digital logic family?

    Classification of the digital logic family Some of the logic families include Resistor-Transistor logic(RTL), Diode-Transistor logic(DTL), Transistor-transistor logic(TTL), Emitter coupled logic(ECL), PMOS, NMOS, and CMOS circuits. They are classified into several types as shown below.

    What is logic family give the classification of logic families in brief?

    Types of Logic Family The logic families which fall under the first kind are called bipolar families, this include diode logic (DL), emitted coupled logic (ECL), resistor transistor logic (RTL), diode transistor logic (DTL), transistor transistor logic (TTL).

    What are 2 major types of logic circuit components?

    There are two basic types of logic circuitry: combinational circuitry and state circuitry. Combinational circuitry behaves like a simple function. The output of combinational circuitry depends only on the current values of its input.

    What is the MOS logic family?

    All the logic gates that are built with MOSFET devices will come under MOS logic family. MOS Logic family can be classified into three categories. They are NMOS logic family – built with N-channel Metal oxide semiconductor FET (MOSFET)

    What are the characteristics of CMOS logic families?

    Characteristics of CMOS Logic Families CMOS supports a very large fan-out, more than 50 transistors. It has excellent noise immunity amongst all families. A logic low voltagefor CMOS is about A logic high voltagefor ECL is somewhere between 4.5V to 5V. The propagation delay is the worst when compared with TTL and ECL families at about 200ns.

    What is CMOS (complementary MOS) logic?

    CMOS (Complementary MOS) logic family uses both N-channel and P-channel MOSFET devices. CMOS has greater complexity than PMOS and NMOS. However, the speed of operation is high and power dissipation is less in CMOS. CMOS also has more fan-out and better noise margin.

    Unipolar Logic Families: It mainly uses Unipolar devices like MOSFETs in addition to passive elements like resistors and capacitors. These logic families have the advantages of high speed and lower power consumption than Bipolar families. These are classified as: PMOS or P-Channel MOS Logic Family
