Question

The primary advantage of RTL technology was that __________

(a) It results as low power dissipation

(b) It uses a minimum number of resistors

(c) It uses a minimum number of transistors

(d) It operates swiftly

This question was addressed to me during an interview.

This is a very interesting question from Register-Transistor Logic(RTL) in chapter Logic Families of Digital Circuits

Answer 1

Correct answer is (c) It uses a minimum number of transistors

Easiest explanation: The primary advantage of RTL technology was that it uses a minimum number of transistors. It consists of registers in large amount and it results in as high power dissipation. The resistors act as the input network and the transistors performs the switching operation.
