The OLF300ET 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
OLF300ET has an LED and an integrated photodiode transistor
detector mounted and coupled in a custom 8-pin hermetic flatpack
package, providing 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 photo transistors by reducing the
base-to-collector capacitance. The internal shield provides
excellent common-mode immunity performance.
