OLS249 optocoupler equivalent, radiation tolerant phototransistor hermetic surface mount optocoupler.
* Hermetic SMT package
* 1500 Vdc electrical isolation
* High current transfer ratio
* Small package size
* High reliability and rugged construction <.
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 / TT.
