Digital Electronics - Engineering

Q1:

Assertion (A): ECL gate has very high speed of operation. Reason (R): Transistors in ECL do not go into saturation region.

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is true, R is false

D A is false, R is true

ANS:A - Both A and R are correct and R is correct explanation of A

Since transistors in ECL do not enter saturation state, switching is fast.
