Which of the following logic families requires maximum power?1 pointTTLCMOSECLIIL

To determine which logic family requires maximum power, we can analyze the power consumption characteristics of each family as follows:

1. TTL (Transistor-Transistor Logic): TTL circuits typically consume more power due to their bipolar transistors. The power consumption is significant when driving larger loads, especially in high-speed applications.

2. CMOS (Complementary Metal-Oxide-Semiconductor): CMOS technology is known for low power consumption. Power is consumed primarily during the switching state; hence, in static states, it consumes very little power.

3. ECL (Emitter-Coupled Logic): ECL is optimized for speed and tends to consume more power than TTL and CMOS because it relies on constant current sources, leading to higher power requirements.

4. IIL (Integrated Injection Logic): IIL logic offers lower power consumption than TTL but generally has power requirements higher than that of CMOS.

Conclusion

Among the listed logic families, ECL (Emitter-Coupled Logic) typically requires the maximum power due to its design and operational characteristics focused on speed rather than power efficiency.
