Question

Which ic in 8085 is used for multiplexing and demultiplexing?

Answer 1

Answer:

The Pin no= 30 of 8085 is the ALE pin which stands for 'Address Latch Enable'. ALE signal is used to demultiplex the lower order address bus (AD0 – AD7). Pins 12 to 19 of 8085 are AD0 – AD7 which is the multiplexed address-data bus. Multiplexing is done to reduce the number of pins of 8085.

Answer 2

Multiplexing is the process in which multiple Data Streams, coming from different Sources, are combined and Transmitted over a Single Data Channel or Data Stream. ... Demultiplexer performs the reverse process of Multiplexing and routes the separated signals to their corresponding Receivers or Destinations.
