The OLS500 is suitable for high-speed digital interfacing applications, elimination of ground loops, and input/output buffering. Each OLS500 has an LED and integrated high-speed detector mounted and coupled in a custom hermetic surface mount leadless chip carrier (LCC) ceramic package that provides 1500 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 OLS500 is 60 ns. The internal shield improves common mode transient immunity to 1000 V/μs minimum.

Device mounting is achieved with reflow soldering or conductive epoxies.
