Question

TTL devices consume substantially ______ power than equivalent CMOS devices at rest.

(a) Less

(b) More

(c) Equal

(d) Very High

This question was posed to me in homework.

This is a very interesting question from Transistor Transistor Logic(TTL) topic in portion Logic Families of Digital Circuits

Answer 1

The correct answer is (b) More

The best I can explain: TTL devices consume substantially more power than equivalent CMOS devices at rest. Thus, CMOS devices are faster than TTL devices.
