#Circuit coder tri state pdf

This is due to the fact that the first input 40 of comparator 38 will have a higher voltage present thereat than at the second input 42. With this voltage level present at the second inputs 42 and 46 of respective comparators 38 and 44, comparator 38 will generate a logic 0 while comparator 44 will generate a logic 1.

In this illustration, this value will be 1.8 v. As a result, the voltage at junction point 22 will be midway between the illustrative 2.8 v and 0.8 v. Now considering the testing in the tri-state condition, the output impedance of gate 10 will assume a high output impedance when a tri-state condition is present.
