OLH500

High CMR, High-speed Logic Gate Hermetic Optocoupler


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.
