NOTES:
OLS 249
Radiation Tolerant
Phototransistor
Hermetic Surface Mount
Optocoupler
The OLS249 consists of a light emitting
diode optically coupled to a NPN silicon
phototransistor mounted and coupled in a
custom hermetic surface mount LCC package.
The very low input current makes the OLS249
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
Special electrical parametric selections are
availabe on request.
Hermetic SMT package
1500 Vdc electrical isolation
High current transfer ratio
Small package size
High reliability and rugged construction
Hi-rel screening available
Radiation tolerant
