Answer / akshay bisht
In tri state devices, used in digital circuits there is a
third state beside logic 0 and logic one. That is called
High Impedance state.
By this state we mean that there will not be any change on
output even by changing our input. THis is due high
resistance offered by input circuit. So output get fixed in
such cases.

Answer / ravichander
we known o state and 1 state and also tristate a node in a
circuit is said to be a high impendence state that node is
not connected either vdd or ground to a low impendence path
a high impendence state used some kind of logic for example
lot of agents to share a common bus that can be achieved by
using multiplexer lot of area congestion instead depends on
tristate logic what means this commonbus share across
multiple agents the only one agent is only driving a bus at
an point of time logically all the other agents are going to
be tristate that bus for area saving when you chips send
bidirectional send a data chip and also receive the data of
achip if you nobody drive some body drive at any ponit of
time that node is floting actully used bushold cell or
buskeeper cell
