DESCRIPTION
The 66138 single channel optocoupler consists of an infrared LED optically coupled to a high gain silicon phototransistor in a
6 pin LCC package. The 66138 is the electrical equivalent of the 4N22U, 4N23U, 4N24U, 4N47U, 4N48U and the 4N49U and
is available as commercial or JAN, JANS, JANTX and JANTXV screened versions.
