NOTES:
OLI 249
Radiation Tolerant
Phototransistor
Optocoupler
For Hybrid Assembly
The OLI 249 is designed especially for hybrid
application requiring optical isolation with high current
transfer ratio and low saturation Vce. Each OLI 249
consists of a light emitting diode and a NPN silicon
phototransistor mounted and coupled in a miniature
custom ceramic package. The very low input current
makes the OLI 249 well suited for direct CMOS to
LSTTL / TTL interfaces. Electrical parameters are
similar to the JEDEC registered 4N49 optocoupler
but with much better CTR degradation characteristics
due to radiation exposure.
Device mounting is achieved by standard
hybrid assembly with non-conductive epoxies. Gold
or aluminum wire bonding can be used to make
electrical connections for maximum placement
flexibility .
Special electrical parametric selections are
available on request.
Current transfer ratio guaranteed over
-55
C to +100
C ambient temp. range
1500 Vdc electrical isolation
Small foot print for hybrid device
More Radiation tolerant than 4N49
