Integrated Circuits Used

74LS04 74LS11

Description

Using 2 triple 3 input AND gate , a NOT gate By considering S0 (input section 0) and S1 (input section 1) as selection lines and pin 5 of input section is considered as input and the pin 10,9,8,7 in output section are considered as outputs respectively Thereby , by connecting as per circuit diagram we'll get a 1X4 de-multiplexer
