SCHEMATIC Features ♦ Electrical parameters guaranteed over -55°C to +125°C ambient temp. range ♦ 1500 Vdc electrical isolation ♦ Low input current - 0.5 mA ♦ Low output saturation voltage - 0.1 V typical ♦ High current transfer ratio - 1000% typical ♦ Low power consumption ♦ Similar to industry standard parts - 6N138 / 6N139 in plastic and 6N140 in hermetic DIP packages ♦ 100% hi-rel screenings are offered PACKAGE OUTLINE Description The OLS 400 has high current transfer ratio at very low input currents making it ideal for applications such as MOS,CMOS, and low power logic interfacing or RS232C data transmission systems. Each OLS 400 has a light emitting diode and a integrated photodiodedarlington detector IC mounted and coupled in a custom hermetic surface mount LCC package providing 1500 Vdc electrical isolation between input and output. The darlington detector has an integrated base to emitter resistor for superior high temperature performance. The split darlington design permits lower output saturation voltage and higher switching speed operation than possible with conventional photodarlington design. Device mounting is achieved with reflow soldering or conductive epoxies. NOTES: 1. Measured between pins 1, 2 and 6 shorted together and pins 3, 4, and 5 shorted together. TA =25 °C and duration = 1 second. 2. Current transfer ratio is defined as the ratio of output collector current, Ic to the forward LED current, IF , times 100%.
