| ISO LINK 6 CATHODE OLS 400 Hermetic Surface Mount Low Input-Current Optocoupler .170.010 .100 .050 5 VCC OLS XXX XXYY 4 VOUT 3 .245.010 4 5 2 6 GND 1 Shield 3 .025 (6 PLS) .080 MAX. SCHEMATIC PACKAGE OUTLINE Features Electrical parameters guaranteed over -55C to +125C ambient temp. range 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. 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 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%. .090 ANODE 1 .065 Absolute Maximum Ratings Coupled Input to Output Isolation Voltage Storage Temperature Range Operation Temperature Range Mounting Temperature Range ( 3 minutes max. ) Input Diode Average Input Current Peak Forward Current ( 1mS duration ) Reverse Voltage Power Dissipation Output Detector Average Output Current Supply Voltage, Vcc Output Voltage, Vout Power Dissipation 1500 Vdc -65C to +150C -55C to +125C 240C 20 mA 40 mA 5.0 V 36 mW 40 mA -0.5 V to 20 V -0.5 V to 20 V 50 mW ELECTRICAL CHARACTERISTIC ( TA = - 55 C to +125 C, Unless Otherwise Specified ) Parameter Current Transfer Ratio Symbol CTR Min 300 300 200 .1 .2 .005 0.6 .01 1.65 3 .4 .4 250 2.0 40 2.0 Typ.
