Question

18 : Consider the following statement 1. ECL has the
least propagation delay 2. TTL has the largest fan
out 3. CMOS has the biggest noise margin 4. TTL
has the lowest power consumption Choose the correct
statement​

Answer 1

plz make me Brilliantist otherwise I'll cry @fks

Answer 2

Among these four statements, 1 and 3 are correct.

The reason for why each statement is correct or incorrect is as follows:

• The propagation delay of Emitter-Coupled logic is 2ns. As transistors never enter saturation, transistors don't get any time to wait for coming out of the saturation point. Thus the first statement is correct.
• The second statement is wrong as TTL has a fan-out of only 10.
• ECL possesses poor while Complementary metal-oxide-semiconductor (CMOS) possesses the biggest noise margin. Thus third statement is correct.

• CMOS has the lowest power consumption. Thus the fourth statement is wrong.
