(7.75) Typ. DESCRIPTION The ILCT6 is a two channel opto isolator for high density applications. Each channel consists of an optically coupled pair with a gallium arsenide infrared LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. .390 (9.91) .379 (9.63) .045 (1.14) .150 (3.81) .030 (.76) .130 (3.30) 4 Typ. .135 (3.43) .115 (2.92) 10 Typ. 3-9 .012 (.30) .008 (.20) .040 (1.02) The ILCT6 is especially designed for driving .022 (.56) .030 (.76 ) medium-speed logic, where it may be used to elimi.018 (.46) .100 (2.54) Typ. nate troublesome ground loop and noise problems. It can also be used to replace relays and transformers in many digital interface applications, as well as Electrical Characteristics (TA=25C) analog applications such as CRT modulation. SymMin. Typ.
