RVUNL EE Quiz 6

Which of the following statement is/are correct.

1) TTL have low power consumption as compared to CMOS IC’s.

2) CMOS IC’s compared to TTL’s are having superior speed characteristics.

Fan out of digital IC is

Consider the following statements, which of the following statement is true?

1) ECL has the least propagation delay.

2) TTL has the largest fanout.

Consider the following logic families:

1) MOS

2) DTL

3) RTL

4) ECL

Arrange these logic families in order of their increasing noise margin.

Each of the next four (4) items consists of two statements, one labelled as ‘Statement (I)’ and the other as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the code given below:

Statement I : Interfacing is the method connecting two electronic device such as logic gates.

Statement II : The problem of voltage incompatibility from TTL to CMOS can be solved by using pull up resistor.

Codes:

A) Both Statements (I) and Statement (II) are individually true and Statement (II) is correct explanation of statement (I).

B) Both Statements (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of statement (I).

C) Statement (I) is true but statement (II) is false.

D) Statement (I) is false but statement (II) is true.

Which of the following logic families has lowest noise margin?
