Which among the following is the fastest switching logic family?1 pointTTLCMOSECLIIL

To determine which of the following logic families has the fastest switching speed, we can analyze each option briefly.

1. TTL (Transistor-Transistor Logic):

   • TTL is faster than earlier technologies like DTL but slower compared to CMOS and ECL.

2. CMOS (Complementary Metal-Oxide-Semiconductor):

   • CMOS is known for its low power consumption and high noise immunity, but its switching speed is slower compared to ECL.

3. ECL (Emitter-Coupled Logic):

   • ECL is designed for high-speed operations and has the fastest switching speed among the common logic families.

4. IIL (Integrated Injection Logic):

   • IIL can be fast but is not as widely recognized or used as ECL for the fastest switching performance.

Final Answer

ECL (Emitter-Coupled Logic) is the fastest switching logic family among the given options.
