The OLS449 is specifically designed for high reliability and space applications that require optical isolation in radiation environments such as gamma, neutron, and proton radiation with a high current transfer ratio (CTR) and low saturation VCE. Each optocoupler consists of an LED and N-P-N silicon phototransistor that is electrically isolated, but optically coupled inside a hermetic six-pin leadless chip carrier (LCC) package.
Electrical parameters are similar to the JEDEC registered 4N49 optocoupler, but with a higher CTR and better CTR degradation characteristics due to radiation exposure.
The OLS449 is designed for a low LED operating current while providing excellent radiation tolerance margins. The OLS449 has 100 percent high-reliability screenings available.
