The OLH500 is suitable for high-speed digital interfacing
applications, elimination of ground loops, and input/output
buffering. Each OLH500 has an LED and integrated high-speed
detector mounted and coupled in a TO-5 hermetic package, that
provides 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. Typical propagation delay for the OLH500 is 60 ns. The
internal shield improves common mode transient immunity to
1000 V/μs minimum.
