infrared emitting diode optically coupled to a monolithic silicon
detector performing the function of a zero voltage crossing bilateral
triac driver.
They are designed for use with a triac in the interface of logic
systems to equipment powered from 115 VAC lines, such as
teletypewriters, CRTs, solid−state relays, industrial controls, printers,
motors, solenoids and consumer appliances, etc.</rdf:li>+ </rdf:Alt>+ </dc:description>+ <xmpMM:DocumentID>uuid:0bcd3264-4e0f-463d-98d7-baf14ce1b55f</xmpMM:DocumentID>+
