Abstract

PURPOSE:To simplify a circuit constitution in the discrimination circuit which can discriminate three states of one input terminal with two states of two output terminals. CONSTITUTION:When input end 1 is high-level Vcc, transistor Tr24 is turned on, and Tr23 and Tr31 are turned off. Consequently, output end 21 becomes low- level signal ''0'', and output end 22 becomes high-level signal ''1''. When input end 1 is middle-level, Tr24, Tr23 and Tr31 are turned on. Consequently, output ends 21 and 22 become low-level signal ''0''. When input end 1 is low-level (ground potential), Tr24 is turned off, and Tr23 and Tr31 are turned on. Consequently, output end 21 becomes high-level signal ''1'', and output end 22 becomes low-level signal ''0''.
