Skyworks Solutions Inc. OLI100 Miniature Phototransistor Optocoupler is designed for hybrid applications that require optical isolation with a high Current Transfer Ratio (CTR) and low-saturation VCE. This optocoupler consists of an LED and an NPN silicon phototransistor mounted and coupled in a miniature custom ceramic package. The OLI100 optocoupler features very low input current making it suitable for direct CMOS to Low Power Schottky Transistor to 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.
