Profile: Isolink, Inc. is the supplier of custom and standard optocouplers and optoelectronic components. Our product line includes photo-transistor, high speed photoDiode-transistor and high-speed MOS-FET driver linear. OLI 100 is designed especially for hybrid application requiring optical isolation with high current transfer ratio and low saturation value. Each OLI 100 consists of a light emitting diode and a NPN silicon photo transistor mounted and coupled in a miniature custom ceramic package. The very low input current makes the OLI 100 well suited for direct CMOS to LSTTL / TTL interfaces. Our OLI 249 is designed especially for hybrid application requiring optical isolation with high current transfer ratio and low saturation Vce. Each OLI 249 consists of a light emitting diode and a NPN silicon photo transistor mounted and coupled in a miniature custom ceramic package. The very low input current makes the OLI 249 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. Device mounting is achieved by standard hybrid assembly with non-conductive epoxies. Gold or aluminum wire bonding can be used to make electrical connections for maximum placement flexibility .
