Special Gates In Digital Electronics. Buffers in digital electronics are special gates inserted between one circuit and another to reduce any unwanted interaction between the two. It has n input n 2 and one output.
These gates can have one input or more than one input but most of the gates have two inputs. Xnor gate is a special type of gate. On the basis of the relationship between the input and the output these gates are named as and gate or gate not gate etc.
The gates in buffer ics typically have high impedance inputs and low impedance outputs giving larger fan out factors than standard gates.
It has n input n 2 and one output. These gates can have one input or more than one input but most of the gates have two inputs. The on resistance of such a switch is in the range of several hundred ohms the off resistance being in the range of several hundred mega ohms. The exclusive or gate is abbreviated as ex or gate or sometime as x or gate.
