(6b) Change the value (xxx) of Select Control Lines and repeat (6a) (Y=Data Line xxx).Д¬lick 'A'(TEXT) button in the Toolbar and write 'Experiment 2', If the Select Contro Line=3 ? Observe also the changes in other Input Lines (0,1,2,4,5,6,7) do not affect (clicking the Binary Switch connected to Input Line 3). Observe change in output values Y and NOT(W) through Binary Probes accoding to changes in Input Line 3 Click NOT(Enable) to 0 (that is, Enable(=1) the device). (6a)Click 3 Binary Switches attached to A,B,C to select one of the Input Lines 0,1,2,3,4,5,6,7: (Observe a connected line will appear as hot (red) line.) (5b)Connect the Output Line, Y, to one Binary Probe, and inverse Output Line NOT(W) to another Binary Probe. NOT(Enable Line) (activate the device), and 3 Select Control Lines, A,B, and C. (5a)Connect 12 Output Lines of Binary Switches to 8 Data Input Lines 0,1,2,3,4,5,6,7, Place 2 Binary Probes on the right hand side of the screen.

Repeat (2a)-(2b) by selecting a Binary Probe. Place 12 Binary Switches on the left hand side of the screen. Repeat (2a)-(2b) by selecting a Binary Switch. Press spacebar to release this operation. The device will now stay in this location and the image will continue to follow your cursor. Point the cursor in the center of the window and click the mouse buttom. Of the selected symbol, in this case 74-151 chip. The cousor will be replaced by a moving image Now move the cursor back into the circuit window. Locate the 74-151 chip (8-to-1 MUX) in the parts list(pull-down menu on the right) and double-click on it. Place this Lab1 Note (Netscape/IE) on the left (1/3 part of the screen) and LW5 on the right. Start the LogicWorks program by double-clicking on the LW5 icon. This is to experiment with some popular 74xx devices in the toolbox of LogicWorks 5. LogicWorks 5 Lab 3 Multiplexer(MUX)s, Encoders and Decoders
