Integrated Circuits Used

74LS10 74LS04 74LS20

Description

Using 2 triple 3 input NAND gate , a NOT gate and a dual 4 input NAND gate By considering S0 (input section 0) and S1 (input section 1) as selection lines and pin 5,6,7,8 of input section are considered as inputs and the pin 0 in output section is considered as output Thereby , by connecting as per circuit diagram we'll get a 4X1 multiplexer
