OLI249 Radiation Tolerant Optocoupler

Skyworks Solutions Inc. OLI249 Radiation Tolerant Optocoupler is designed for hybrid applications that require optical isolation with a high Current Transfer Ratio (CTR) and low-saturation V_CE. This optocoupler consists of an LED and NPN silicon phototransistor that is mounted and coupled in a miniature custom ceramic package. The OLI249 optocoupler features low input current making it suitable for direct Complementary Metal Oxide Semiconductor (CMOS) to Low Power Schottky Transistor-Transistor Logic (LSTTL)/TTL interfaces. The device is mounted by standard hybrid assembly with nonconductive epoxies. Preferably gold or aluminum wire bonding can be used to make electrical connections for maximum placement flexibility. Typical applications include avionics, biomedical materials, radar, space, surveillance systems, instrumentation, and military communications.
