The DTL, TTL, ECL and CMOS families of digital ICs are compared in the following 4 columns–
(P) (Q) (R) (S) A. Fan out is minimum DTL DTL TTL CMOS B.Power consumption is minimum TTL CMOS ECL DTL C. Propagation delay is minimum CMOS ECL TTL FTL
The correct column is—
-
- P
- R
- Q
- S
Correct Option: B
Fan out is minimum → DTL
Power consumption is minimum → CMOS
Propagation delay is minimum → ECL
Hence alternative (B) is correct choice.
