Abstract
PURPOSE:To simplify the circuit by controlling 4 transistors(TRs) of the tri-state value transmission driver circuit through the direct drive of 3-state input levels thereby sending a tri-state code and eliminating the need for the circuit of binary control. CONSTITUTION:Four TRs 11, 21, 13, 24 are turned on/off by the direct drive of input levels of three values, 0V, 2V and 4V and the two TRs 11, 21 are on/off-controlled by a diode 31 of a level shift means 3. Moreover, the level of the TR 24 is shifted to the collector of the TR 31 by a diode 32 of the level shift means 3 to output the tri-state codes of 4V, 2V, 0V.
