66189

66189 Revision B RADIATION TOLERANT OPTOCOUPLER PIN FOR PIN REPLACEMENT FOR 3C91C 7/14/00 Mii OPTOELECTRONIC PRODUCTS DIVISION Features: High Reliability Base lead eliminated for improved noise immunity Proton & Total Dose Tolerant Stability over wide temperature +500V electrical isolation Applications: Eliminate ground loops Level shifting Line receiver Switching power supplies Motor control 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.
