+# Demux IC
+
+Demux is the de-multiplexer circuit that takes one input line and gives multiple output lines. Basically, it’s a combinational circuit and It always takes one input
+line and gives 2n output line, where n is the number of select lines. It is also, known as a serial to parallel converter or data distributor circuit. The 1:2 Demux consist of 1 input line, 1 select line, and produces 2 output line. as, according to the formula no. of the output line is depends on no. of select line, here, in 1:2 demux, no. of output line = 2^n = 2^1 = 2.
+
+
+## Usage/Examples
+
+It is used in communication systems. 
+
+It is used in serial to parallel converter.
+
+
+## Documentation
+
+To know the details of 74LVC1G19 IC please refer to this link [74LVC1G19_IC_datasheet.](https://assets.nexperia.com/documents/data-sheet/74LVC1G19.pdf)
+
+## Comments/Notes
+
+Please note this is a complete Digital IC. It works fine at the time of simulation.
