OLH300

High-speed Hermetic Optocoupler

The OLH300 is suitable for interfacing Transistor-Transistor Logic (TTL) to Low Power Schottky Transistor-Transistor Logic (LSTTL), TTL, or Complementary Metal Oxide Semiconductor (CMOS), as well as wide bandwidth analog applications.

Each OLH300 has an LED and an integrated photodiode transistor detector that is mounted and coupled in a ceramic substrate inside a hermetic TO-5 package that provides 1000 VDC of electrical isolation between the input and output. The integrated photodiode transistor improves the switching speed by orders of magnitude as compared to standard phototransistors by reducing the base-to-collector capacitance. The internal shield provides excellent common-mode immunity performance.
