DESCRIPTION
The
66189
contains a proton tolerant LED optically coupled to a silicon photodiode detector circuit. The optocoupler is built
on a TO-72 header. The anode of the LED is electrically connected to the case. This optocoupler is capable of transmitting
signals between two galvanic sources. The potential difference between transmitter and receiver should not go over the
maximum isolation voltage. The internal base connection has been eliminated for improved noise immunity.
