Abstract
A logic circuit for converting a triple state input to a binary output having a single line ternary input and a two line binary output. A pair of output transistors provide the two line binary output, and means are provided for driving both of these output transistors, such that three different binary output states result from the ternary input states of low, high and open (or floating), respectively.
