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.
Note: Data is maintained by an independent source and accuracy is not guaranteed.Check with the manufacturer's datasheet for up-to-date information. Apr 19, 2016 · 10. Note BCD output from the IC 74148 as the input to 74138. 11. Compare the truth table. 12. Note outputs of decoder truth table. RESULT: Thus the operation of 8 to 3 line Encoder and 3 to 8 Decoder using IC 74138, 74148 truth tables are verified. 3-to-8 line decoder/demultiplexer Rev. 5 — 13 June 2018 Product data sheet 1 General description The 74HC238; 74HCT238 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1 and E2 and E3). Every output will be LOW unless E1 and E2 are LOW and E3 ... 74LS138 / 74LS138-SMD / 74LS139 Decoder/Demultiplexer General Description These Schottky-clamped circuits are designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In high-performance memory systems these decoders can be used to minimize the effects of system decoding ... 74LS138, 74LS138 Datasheet, 74LS138 3 to 8 Decoder Datasheet, buy 74LS138 Decoder
