8 PIN DIP LOW INPUT CURRENT HIGH GAIN 6N138 6N139 SPLIT DARLINGTON PHOTOCOUPLER Features: High current transfer ratio2000% typical High isolation voltage between input and output (Viso=5000 Vrms ) Guaranteed performance from 0C to 70C Pb free and RoHS compliant. UL approved (No. 214129) VDE approved (No. 132249) SEMKO approved NEMKO approved DEMKO approved FIMKO approved CSA approved (No. 2037145) Description The 6N138 and 6N139 devices each consists of an infrared emitting diode, optically coupled to a high gain split Darlington photo detector. They provide extremely high current transfer ratio between input and output, with access to a base terminal to adjust the gain bandwidth. Schematic These devices are packaged in an 8-pin DIP package and available in wide-lead spacing and SMD options. 1 8 Applications 2 7 Digital logic ground isolation 3 6 RS-232C line receiver Low input current line receiver 4 Microprocessor bus isolation 5 Current loop receiver Pin Configuration 1.
