contains an infrared LED optically coupled to a silicon phototransistor in a hermetic 4 lead TO-18 package. The
collector of the phototransistor is electrically connected to the case. The internal base connection has been eliminated for
improved noise immunity. The 3N261, 3N262 and 3N263 can be supplied to commercial or screened quality levels as well as
to customer specifications.
