Objective: To demonstrate the operation of a digital multiplexer. Device List: Binary switch Binary And 2 Not Or_2 74_151 Mux-4 wo/en Probe EN 151 DEV2 Table 1 INPUTS OUTPUT A X1 xo Y 8-line to 1-line data selector/multiplexer lo lo 10 10 lo 1 A1. Connect the circuit shown in Fig. 9.1. Apply the inputs A, X0 and X1 as in Table 1 with 10 1 10 data switches. Monitor the output Y with the probe and record the output for each set of inputs in Table 1. 1 1 1 0 lo 1 A 1 10 X1 1 1 Q1. What type of circuit is this? Q2. The control (addressing) input is. Fig. 9.1 Q3. If A is in position 0, what is the effect of X0 on the output Y?_ Q4. What is the state of Y, if A is 1, which input is enabled X1/X0)? ._ Q5. The multiplexer concept is not limited to two data imputs. With the circuit in Fig. 9.1, we can control 2 data input. If we add a second addressing input, we can control data inputs. A2. Connect the circuit shown in the Fig. 9.2. This circuit uses a TTL type 74151 chip (8-to-1 MUX). Connect binary switches to 8 data input lines (0-7), Not Enable Line (for activating device) and 3 select control signal (A, B, and C). Connect the output line, Y, to one binary probe and inverse output line Not W to another binary probe. Click 3 binary switches attached to A, B, C to select one of the input lines 0-7: Such as A=1, B=1, C=0 (that is select line 3 (011)). Observe the operation of the multiplexer. A3. Set select lines (SLO-SL2) to 000. Determine which input (DO through D7) on the 74151 is enabled with this binary code. Then operate each of the data switches SW0 through SW7 and determine which switch causes a change in the binary probe. Continue altering the select lines for all eight states and complete the Table 2 as indicated. The first one is given as an example.
