74138 datasheet truth table solver

2.1.1 Prepare a truth table of the given function f and of its complement f, and show them as Table T2.1-1. Hint#1 To avoid unnecessary loss of time while completing some later parts of the assignment, remember that the designation f(D,C,B,A) implies that the list of variables in the truth table of the function is in the order D,C,B,A.

Jul 23, 2015 · The truth table of a 1-to-2 demultiplexer is shown below in which the input is routed to Y0 and Y1 depends on the value of select input S. In the table output Y1 is active when the combination of select line and input line are active high, i.e., S F = 11. Therefore, the output Y1 = SF and similarly the output Y0 is equal to S ̅ F.
