I believe what you are referencing is when a pin to an IC is left with no connection. Depending on the application, often an input(s) or an output(s) is not used. In such a scenario it is good practice, and in the case of CMOS devices necessary, to tie the unused pin(s) to logic high or low using pull-up or pull-down resistors. The choice of tying to high or low will be dictated by the application and the IC's data sheet will offer guidance.
In linear IC'S the output voltage is very according to input voltage In digital IC's the output voltage is either high or low
The best way to understand the working of a specific IC is to look at the datasheet for that IC. Just search for it on the Internet. That being said, it is a 2 input NAND gate which is capable of transforming slow changing input signals into jitter-free output signals.
The 7432 is a quad two input OR gate with TTL levels.
Darlington circuit is voltage follower circuit with high input impedance and low output impedance.Darlington IC must have this ciruit integrated on it..
strobe is enable input in a digital IC...if its made active high...it will be enabled..some IC strobe is active low.. Its function is to enable the operation of the IC..or gate or Mux...
For two input AND gate it is 7408for three input AND gate it is 7411
In linear IC'S the output voltage is very according to input voltage In digital IC's the output voltage is either high or low
It will give high output when the given input is low and also give LOW output when the given input is high (Vice versa).

in the IC-7805 i need a meaning for the number 7,8,0,5 seperately
A: It is a 14 pins dual in line quadruple 2 input positive NOR Gates. It BELONG TO THE 74XX family of IC
fets are used in linier ic's to 1)to provide large resistences 2)increase input resistence
The 7400, and its variations, is a quad two input NAND gate.
The 7432 is a quad two input OR gate with TTL levels.
The problem with floating inputs is that electrical noise in the line could trigger the input without user input. This can easily be avoided with a pull-up or pull-down resistor. The problem with floating inputs is that electrical noise in the line could trigger the input without user input. This can easily be avoided with a pull-up or pull-down resistor.
the output of 7805 is 2v or 3v if we give the input as 2v or 3v.
