Q1:

What must be done in the given figure in order to use two 7485 4-bit comparators to compare two 8-bit numbers?

A The P < Q, P = Q, and P > Q outputs of COMP A must be connected to the same outputs of COMP B.

B The P < Q, P = Q, and P > Q outputs of COMP A must be connected to the <, =, and > inputs of COMP B.

C The = input of COMP A must be connected to Vcc, and the < and > inputs must be connected to ground.

D The P < Q, P = Q, and P > Q outputs of COMP A must be connected to the <, =, and > inputs of COMP B, the = input of COMP A must be connected to Vcc, and the < and > inputs must be connected to ground.

ANS:D - The P < Q, P = Q, and P > Q outputs of COMP A must be connected to the <, =, and > inputs of COMP B, the = input of COMP A must be connected to Vcc, and the < and > inputs must be connected to ground.
