Question

Fan-in and Fan-out are the characteristics of ___________

(a) Registers

(b) Logic families

(c) Sequential Circuits

(d) Combinational Circuits

This question was posed to me in an interview for job.

I need to ask this question from Digital Integrated Circuits topic in portion Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

Right answer is (b) Logic families

To explain I would say: Fan-in and Fan-out are the characteristics of logic families. Fan-in is the measure of maximum number of inputs that a single gate output can drive or accept. Whereas, Fan-out means the maximum number of inputs that can be fed by a single output.
