Draw a schemetic to demultiplex bus ad0-ad7 using any octal latch in 8085 microprocessor?

The 8085 microprocessor is used IC 74LS373 to latch the address of 8085. Basically latch is consists of 8 flip flops. Generally we used D-flip flops (Delay).

The clock of these flip flops are connected together and available as a output pin called enable.

Working : The address will appear on AD0 AD7 lines. The ALE will go high and forcing

Enable = 1. This will make latch enable and ready to work. Before address disappears ALE = 0. This will make latch disable. AD0 - AD7 will now be used as data bus.

Hence, AD0 - AD7 (low order) address bus of the 8085 microprocessor is multiplexed (time-shared) with the data bus. The buses need to be demultiplexed.
