Description:
Each device is a high reliability optically coupled isolator that consists of an infrared emitting diode and a NPN silicon phototransistor which are mounted in a hermetically sealed TO-72 package. The 3C91C and 3C92C have a 935 nm wavelength, whereas the 3N243, 3N244, 3N245, 3N261, 3N262 and 3N263 have an 880 nm wavelength. All devices have 0.50” (12.70 mm) leads. Electrical characteristics vary. The 3N261TX, 3N262TX and 3N263TX devices are similar to JEDEC registered optically coupled isolators.
