What are the fastest logic families?

What are the fastest logic families?

Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as the fastest logic available.

Which logic gate operates the fastest?

3 Answers. ECL is both the fastest logic family and has the simplest internal structure of modern logic families, but like other bipolar-only families it has a not insignificant power draw.

Which digital logic family has better performance?

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.

Which logic family is faster TTL or ECL?

ECL | Emitter Coupled Logic ECL eliminates saturation and improves speed but uses more power than other logic families such as TTL and CMOS. ECL is fastest logic family among all and this is due to avoidance of saturation region for application.

Which logic family is slow?

Monolithic integrated circuit logic families compared

Family Description Remarks
TTL L Low power
TTL H High speed
TTL S Schottky high speed
TTL LS Low power Schottky high speed

Which logic family has highest fan out?

CMOS have highest fan out.

  • Fan-out is a term that defines the maximum number of digital inputs that the output of a single logic gate can feed.
  • Fanout for CMOS gates, is the ratio of the load capacitance (the capacitance that it is driving) to the input gate capacitance.

    • Which logic family has maximum fan out?

    CMOS
    Detailed Solution. gates. CMOS has the maximum fan-out capacity. Fan-Out is the maximum number of inputs that can be connected to the output of a gate without affecting the normal operation.

    Which logic family has least propagation delay?

    TTL
    Among the given options, TTL has the least propagation delay.

    Which logic is the fastest of all the logic families Mcq?

    Emitter Coupled Logic
    Explanation: ECL stands for Emitter Coupled Logic. It is the fastest of all the logic families because of its higher transmission rate.

    Which logic family is fastest power dissipation?

    ECL is about the fastest, and CMOS the lowest power.It is fastest digital logic family. Its greatest disadvantage is greater power dissipation. Hence the speed power factor is very less in ecl.

    Which is fastest among all logic families Why?

    Emitter-coupled-logic (ECL) is a BJT logic family that is generally considered the fastest logic available. ECL achieves its high-speed operation by employing a relatively small voltage swing and preventing the transistors from entering the saturation region.

    Which logic family is advanced one?
