MULTIPLEXER
AIM:
To construct and verify the operation of multiplexer circuit using logic
gates.
APPARATUS REQUIRED:
S.NO | COMPONENTS | RANGE | QUANTITY |
1 | Digital Trainer Kit | 1 | |
2 | IC 7404 | 1 | |
3 | IC 7408 | 1 | |
4 | IC 7432 | 1 | |
5 | Connecting wires | As required |
CIRCUIT DIAGRAM:
4-to-1 Multiplexer
Logic diagram
PROCEDURE:
1. Circuit connections are given as per the circuit diagram.
2. The +5V DC power supply is properly connected to Vcc and GND
pins(14 & 7) of each IC.
3. Logical input conditions are given as per the Function Table.
4. Logical outputs are observed and verified.
RESULT:
Thus the Multiplexer circuit is constructed and the output is verified using the Function Table.

SHIFT REGISTER
AIM:
To construct and verify the operation of a 4 bit serial in parallel out shift register.
APPARATUS REQUIRED:
S.NO | COMPONENTS | RANGE | QUANTITY |
1 | Digital Trainer Kit | 1 | |
2 | IC 7474 | 2 | |
3 | Connecting wires | As required |
CIRCUIT DIAGRAM:
4 bit Serial in Parallel out shift register
Truth Table:
Clock | Serial i/p | Q1 | Q2 | Q3 | Q4 |
0 1 2 3 4 | 0 1 0 1 0 | 0 1 0 1 0 | 0 0 1 0 1 | 0 0 0 1 0 | 0 0 0 0 1 |
PROCEDURE:
1. Circuit connections are given as per the circuit diagram.
2. The +5V DC power supply is properly connected to Vcc and GND pins
(14 & 7) of each IC.
3. The pulse generator is connected to CLK inputs of all the Flip Flops.
4. The data input (1010)to verify the truth table is given to D input of the
Flip Flop and clock pulse is given.
5. The outputs are verified from the ON or OFF condition of the LED.
RESULT:
Thus the 4 bit serial in parallel out Shift Register circuit is constructed and the output is verified using the Truth Table.
