It's a programmable, general-purpose input/output device designed for the Intel 8080A/8085A processor lines. Basically it's a chip you can use as interface to various other electronics - storage, displays, ports etc. It has some features (like the ability to drive printer and display interfaces directly) that make it a one-stop solution to interfacing with many devices (that is why it's general-purpose).
What you do is send data from the CPU to this chip, and then switch its communications to another chip - the D8255AC has various interface options (and so is programmable) for different methods of communication that it will handle for you. It can be an input, an output, or both. You can hook up many devices (other chips) to it at the same time and communicate with them accordingly.
The D8255AC-2 is the 5MHz system clock variant (there is a 4MHz variant, the D8255AC-5).
Please keep in mind that you still have to make input/output levels (voltages) match, by using other chips in-line if required.
can i use ic 7476 as time delay
Because , it will be easier to use , remove & replace a cascaded ic .

WHAT IS THE PURPOSE OF IC 4027 IN SWITCHING CIRCUIT
Because , it will be easier to use , remove & replace a cascaded ic .
it is an ic used for generating pulses.its circuit has resembalance with the circuit of flip-

It depends on which 32pin IC you use. Please restate the question.

use two of them for 8 bits.
IC 7806 is the voltage regulator that gives 6V dc voltage from 230V ac power supply. It is used to give power supply to the IC which operates on 6V.
pin1to 8 is used in ic741
its cheap and easy to use.
