OLH300

High Speed

Hermetic

Optocoupler

-55

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-

diode transistor detector mounted and coupled

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.

1. Measured between pins 1,2 and 3 shorted together and pins 5,6 and 7 shorted together. T

2. Current transfer ratio is define as the ratio of output collector current, Ic to the forward LED current, IF times 100%
