Which logic family provides high speed?
Which logic family provides high speed?
Emitter-coupled-logic (ECL): 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 is fastest among all logic families Why?
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.
Which logic family has high propagation delay?
CMOS is the standard logic family used in most ICs except in specialized applications. Compared to TTL and its sub-families, ECL is a much faster architecture with propagation delay reaching ~1 ns, and it was widely used in computing architecture for some time.
Which logic family is fastest power dissipation?
Emitter-coupled-logic (ECL) is a BJT logic family that is generally considered the fastest logic available.
Which logic family has the highest power dissipation?
(a); ECL has the highest power dissipation.
Which family has fastest speed?
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.
How many 16K RAMs are required to achieve a memory with a capacity of 64K and a word length of 8 bits?
512K RAM
Explanation: 16K * 4 = 64K RAM is of 64K. Therefore, for a word of length 8-bits, 64 * 8 = 512K RAM required. Thus, number of 16K * 4 RAMs = 512/64 = 8.
Which logic gate has higher speed?
Infact the logic gate which is considered to be the fastest is Emitter-coupled logic (ECL).
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 slow?
Disadvantages of CMOS logic family- Slow operating speed – The main disadvantage of CMOS logic family is their slow speed of operation. Propagation delay time for CMOS family is found to around 50ns whereas it is around 4 to 12 ns for TTL logic family.
Is CMOS faster than TTL?
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 family consumes maximum power?
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.
