Features
Description
♦ Electrical parameters guaranteed over
-55°C to +125°C ambient temp. range
♦ 1000 Vdc electrical isolation
♦ High-Speed, 1 Mbit/s typical
♦ Open collector output
The OLH 300 is suitable for interfacing TTL to
LSTTL, TTL or CMOS as well as wide band-
width analog applications. Each OLH 300 has
a light emitting diode and an integrated photo-
diodetransistordetectormountedandcoupled
in a ceramic substrate inside a hermetic TO-5
package providing 1000 Vdc electrical isola-
tion between input and output. The integrated
photo-diode transistor improves 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 im-
munity performance.
♦ 300 Khz bandwidth
♦ TO - 5 hermetic package
♦ Similar to 6N135/136, 4N55
♦ Radiation tolerant
♦ 100% hi-rel screening are offered
NOTES:
1. Measured between pins 1,2 and 3 shorted together and pins 5,6 and 7 shorted together. TA = 25 °C and duration = 1 second.
2. Current transfer ratio is define as the ratio of output collector current, Ic to the forward LED current, IF times 100%
