Description
Features
The OLF300 is suitable for interfac-
ing TTL to LSTTL, TTL or CMOS as well
as wide bandwidth analog applications.
Each OLF300 has a light emitting diode
and an integrated photo-diode transistor
detector mounted and coupled in a cus-
tom 8-pin hermetic flat pack package
providing 1000 Vdc electrical isolation
between input and output. The integrated
photo-diode transistor improves switching
speed by orders of magnitude as com-
pared to standard photo transistors, by
reducing the base to collector capaci-
tance. The internal shield provides excel-
lent common-mode immunity perfor-
mance.

NOTES:
1. Measured between pins 1, 2 and 6 shorted together and pins 3, 4, and 5 shorted together. TA =25 °C and duration = 1 second.
2. Current transfer ratio is defined as the ratio of output collector current, Ic to the forward LED current, IF , times 100%.
