Q1: Which of the following summarizes the important features of emitter-coupled logic (ECL)?

A negative voltage operation, high speed, and high power consumption

B good noise immunity, negative logic, high frequency capability, low power dissipation, and short propagation time

C slow propagation time, high frequency response, low power consumption, and high output voltage swings

D poor noise immunity, positive supply voltage operation, good low-frequency operation, and low power

ANS:A - negative voltage operation, high speed, and high power consumption

Emitter coupler is one of the commenly used configeration because of -ve voltage operation & high speed operation.
