HCPL-2730 Datasheet | Fairchild Semiconductor

DESCRIPTION The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist of an Al Ga As 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, HCPL-2730/HCPL2731, an integrated emitter - base resistor provides superior stability over temperature. The bination of a very low input current of 0.5 m A 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 patibility is ensured to CMOS as well as high fan-out TTL requirements. An internal noise shield provides exceptional mon mode rejection of 10 k V/µs. An improved package allows superior insulation permitting a 480 V working voltage pared to industry standard 220 V. 8 1 DUAL-CHANNEL HCPL-2730 HCPL-2731 8 1 8 1 FEATURES - - - - - - - Low current - 0.5 m A Superior CTR-2000% Superior CMR-10 k V/µs Double working voltage-480V RMS CTR guaranteed 0-70°C U.L. recognized (File # E90700) Dual Channel - HCPL-2730 HCPL-2731 APPLICATIONS - - - - - - Digital logic ground isolation Telephone ring detector EIA-RS-232C line receiver High mon mode noise line receiver µP bus isolation Current loop receiver N/C 1 8 VCC + 1 V F1 8 VCC + 2 VF _ 3 7 VB _ 2 7 V01 6 VO _ VF2 6 V02 N/C 4 5 GND + 4 5 GND 6N138 / 6N139 HCPL-2730 / HCPL-2731 ABSOLUTE MAXIMUM RATINGS Parameter Storage Temperature Operating Temperature Lead Solder Temperature EMITTER DC/Average Forward Input Current (No derating required up to 85°C) Symbol TSTG TOPR TSOL Each Channel Each Channel IF (avg) IF (pk) IF (trans) Each Channel Each Channel Each Channel (6N138 and 6N139) (6N138, HCPL-2730) (6N139, HCPL-2731) Each Channel VR PD IO (avg) VEB VCC, VO PD Value -55 to...
