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.
