Data Sheet HCPL-2730/0730/2731/0731 Dual-Channel Low Input Current, High-Gain Optocouplers Overview Features These dual-channel optocouplers contain a separated pair High current transfer ratio 1800% typical of GaAsP light-emitting diodes optically coupled to a pair of Low input current requirements 0.5 mA integrated high-gain photodetectors. They provide Low output saturation voltage 0.1V extremely high current transfer ratio and excellent High density packaging input-output common mode transient immunity. A separate Performance guaranteed over temperature 0C to 70C pin for the photodiodes and first gain stages (V ) permits CC LSTTL compatible lower output saturation voltage and higher speed operation High output current 60 mA than possible with conventional photo-darlington type Safety approval: optocouplers. In addition, V may be as low as 1.6V CC UL recognized 3750 V rms for 1 minute and without adversely affecting the parametric performance. 5000 Vrms (see Note) for 1 minute CSA approved These dual-channel optocouplers are available in an 8-pin DIP and in an industry standard SO-8 package. The Available in 8-pin DIP and SO-8 footprint following is a cross reference table listing the 8-pin DIP part MIL-PRF-38534 hermetic version available number and the electrically equivalent SOIC-8 part number. (HCPL-5730/5731) Surface mount gull wing option available for 8-pin DIP (Option 300) 8-Pin DIP SO-8 HCPL-2730 HCPL-0730 NOTE: 5000 V rms/1 minute withstand voltage rating is for HCPL-2731 HCPL-0731 Option 020 (HCPL-2730, HCPL-2731) products only. The SO-8 does not require through holes in a PCB. This Applications package occupies approxmately one-third the footprint area of the standard dual-inline package. The lead profile is Digital logic ground isolation designed to be compatible with standard surface mount Telephone ring detector processes.

Guaranteed operation at low input currents and the high current transfer ratio (CTR) reduce the magnitude and effects of CTR degradation. The outstanding high temperature performance of this split Darlington-type output amplifier results from the inclusion of an integrated emitter-base bypass resistor that shunts photodiode and first stage leakage currents to ground. The HCPL-2731/0731 have a 400% minimum CTR at an input current of only 0.5 mA making it ideal for use in low input current application, such as MOS, CMOS, and low-power logic interfacing or RS232C data transmission systems. In addition, the high CTR and high output current capability make this device extremely useful in applications where a high fanout is required. Compatibility with high-voltage CMOS logic systems is guaranteed by the 18V V and V specifications CC O and by testing output high leakage (I ) at 18V. OH The HCPL-2730/0730 are specified at an input current of 1.6 mA and have a 7V V and V rating. The 300% minimum CC O CTR allows TTL to TTL interfacing at this input current. Important specifications, such as CTR, leakage current, and output saturation voltage, are guaranteed over the 0C to 70C temperature range to allow trouble-free system operation. Selection for lower input currents down to 250 A is available upon request. Broadcom AV02-0546EN 2
