DATA SHEET www.onsemi.com 8-Pin DIP Low Input Current High Gain Split Darlington Optocouplers Single-Channel: 6N138M, 6N139M Dual-Channel: HCPL2730M, HCPL2731M PDIP8 6.6x3.81, 2.54P CASE 646BW 8 1 PDIP8 9.655x6.6, 2.54P CASE 646CQ 8 1 Description The single−channel, 6N138M, 6N139M and dual−channel HCPL2730M, HCPL2731M optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector. The split darlington configuration separating the input photodiode and the first stage gain from the output transistor permits lower output saturation voltage and higher speed operation than possible with conventional darlington phototransistor optocoupler. In the dual channel devices, HCPL2730M and HCPL2731M, an integrated emitter−base resistor provides superior stability over temperature. The combination of a very low input current of 0.5 mA and a high current transfer ratio of 2000% makes this family particularly useful for input interface to MOS, CMOS, LSTTL and EIA RS232C, while output compatibility is ensured to CMOS as well as high fan−out TTL requirements. An internal noise shield provides exceptional common mode rejection of 10 kV/ms. Low Current – 0.5 mA Superior CTR – 2000% Superior CMR – 10 kV/ms CTR Guaranteed 0 to 70°C Dual Channel – HCPL2730M, HCPL2731M Safety and Regulatory Approvals UL1577, 5,000 VACRMS for 1 Minute DIN EN/IEC60747−5−5 These are Pb−Free Devices October, 2022 − Rev. 2 6N138 VXXYYB 6N138 V = Device Number = DIN EN/IEC60747−5−5 Option (only appears on component ordered with this option) = Two−Digit Year Code, e.g., ‘16’ = Two−Digit Work Week, Ranging from ‘01’ to ‘53’ = Assembly Package Code ORDERING INFORMATION See detailed ordering and shipping information on page 11 of this data sheet.
