1.	What is the difference between 7490 and a 7492?(a) 7490 is a MOD-12, 7492 is a MOD-10(b) 7490 is a MOD-12, 7492 is a MOD-16(c) 7490 is a MOD-16, 7492 is a MOD-10(d) 7490 is a MOD-10, 7492 is a MOD-12This question was addressed to me during an internship interview.The above asked question is from Counter ICs topic in division Counters of Digital Circuits
Answer» RIGHT ANSWER is (d) 7490 is a MOD-10, 7492 is a MOD-12 The explanation is: From the properties of both ICs, we have 7490 is a MOD-10, 7492 is a MOD-12. THUS, IC-7490 can have maximum 10 states, while IC-7492 can have maximum 12 states.
