High CMR, High-speed Logic Gate Hermetic Surface Mount Optocoupler

The OLF500 is suitable for high-speed digital interfacing applications, elimination of ground loops, and input/output buffering in a hermetic surface mount technology (SMT) package. Each OLF500 has an LED and integrated high-speed detector that is mounted and coupled in a custom 8-pin hermetic flat-pack package, providing 1000 VDC electrical isolation between the input and output. The light from the LED is collected by the photodiode in the integrated detector, and amplified by a high-gain linear amplifier that drives a Schottky-clamped open collector output transistor. The internal shield improves the common mode transient immunity to a minimum of 1000 V/μs.
