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 transmis-
sion systems. Each OLS 400 has a light
emitting diode and a integrated photodiode-
darlington 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
