Description
The OLS2449 is specifically designed for high-reliability applications that require optical isolation in radiation environments such as gamma, neutron, and proton radiation with high CTR and low saturation VCE. Each optocoupler channel consists of an LED and N-P-N silicon phototransistor that is electrically isolated, but optically coupled inside a hermetic eight-pin Leadless Chip Carrier (LCC) package.
The electrical parameters are similar the JEDEC registered 4N49U optocoupler, but with a higher CTR and better CTR degradation characteristics due to radiation exposure.
The OLS2449 has 100 percent high-reliability screening parts available (contact Isolink for more information).

FEATUREs

   – Guaranteed over –55 °C to +100 °C ambient temperature
      range
   – High at low LED currents
● High BVCEO, 65V minimum
● 1500 VDC electrical isolation
● High-reliability screening is available
