Question

Compared to TTL, CMOS ICs have

• A. Higher power consumption
• B. Lower noise immunity
• C. Higher input impedance
• D. Lower packing density

Hint:

Compared to TTL, CMOS ICs have \[ \boxed{ \text{Higher input impedance, lower power consumption, and better noise immunity.} } \]

Answer 1

The Correct Option is C

Step 1: Recall the characteristics of CMOS ICs. Compared to TTL ICs, CMOS ICs have - very high input impedance, - low power consumption, - high noise immunity, - high packing density.

Step 2: Choose the correct option. Therefore, \[ \boxed{\text{Higher input impedance}} \] is the correct answer. Hence, \[ \boxed{(C)} \] is the correct answer.
