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.
