## Which logic family is fastest?

Emitter-coupled logic

Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as 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 supports high-speed of operation?**

A faster logic family called FAST (Fairchild Advanced Schottky TTL) (Schottky) (F) was also introduced that was faster than normal Schottky TTL.

### Which logic family has highest fan out capacity?

CMOS have highest fan out.

**Which logic family has lowest power consumption?**

The logic family with the lowest power dissipation is

- TTL.
- DTL.
- CMOS.
- ECL.

#### Which is faster TTL or CMOS?

TTL chips are generally faster than CMOS gates (but see ACT series), however there are two logic technologies faster than TTL-Emitter-coupled logic (ECL) and gallium arsenide (GaAs). These chips come at considerable cost in power consumption and ease of interface to other logic families.

**Which logic gate is faster?**

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 gate has highest speed?

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 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 has least propagation delay?

TTL

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

**Which of the following is fastest logic style?**

Explanation: ECL is the fastest of all the logic families because of the emitters of many transistors are coupled together which results in the highest transmission rate.

#### What is the major advantage of CMOS logic?

The main advantage of CMOS logic family is their extremely low power consumption. This is because there is no direct conducting path from Vdd to ground in either of input conditions. So there is practically zero power dissipation in STATIC conditioms.

**What is difference between CMOS and TTL?**

TTL circuits utilize BJTs while CMOS circuits utilize FETs. 2. CMOS allows a much higher density of logic functions in a single chip compared to TTL. TTL circuits consumes more power compared to CMOS circuits at rest.

## Which is the best type of logic family?

Emitter Coupled Logic (ECL), also referred to as Current Mode Logic families, is a digital technology with extremely high-speed. Transistors are not allowed to go into deep saturation thus, eliminating storage delays like in TTL logic families.

**Which is the fastest family of logic chips?**

The ECL (Emitter Coupled Logic) families, originated in the late 1950s and remain the fastest chips available, but consume more power, and because they use a negative power supply (of −5.2V) have been difficult to interface with other families.

### Can a logic family be connected to a sub family?

Making direct connections between ICs of a single family or sub family is usually very simple. ICs of different families can sometimes also be directly connected together, but may require some extra circuitry at the interface of the two IC families to maintain compatibility.

**What are the advantages of the TTL logic families?**

Advantages of the TTL logic families include high switching speed (125 MHz), less noise and more current (3 mA) driving capability. Figure shows TTL NAND gate.
