16 to 1 multiplexer using ic 74151 - (ic 74150)

abstract:

to study and simulate design of ic 74150 using vhdl.

theory:

multiplexer ic 74151 is 8 to 1 multiplexer. it has 8 inputs and only one output based on the select inputs a, b, c it steers one of the input to the output y. in 16 to 1 multiplexer design we use two 74151 ic

Can u please send me the circuit diagram in multisim

THEORY:



Multiplexer is a combinational circuit that is one of the most widely used in digital design.
The multiplexer is a data selector which gates one out of several inputs to a single o/p. It has n data inputs & one o/p line & m select lines where 2m= n shown in fig a.
Depending upon the digital code applied at the select inputs one out of n data input is selected & transmitted to a single o/p channel.
Normally strobe (G) input is incorporated which is generally active low which enables the multiplexer when it is LOW. Strobe i/p helps in cascading.
IC 74151A is an 8: 1 multiplexer which provides two complementary outputs Y & Y. The o/p Y is same as the selected i/p & Y is its complement. The n: 1 multiplexer can be used to realize a m variable function. (2m= n, m is no. of select inputs)
