DESCRIPTION
The IS66_ series are optically coupled isolators
consisting of infrared light emitting diode and a
high voltage NPN silicon photo darlington which
has an integral base-emitter resistor to optimise
switching speed and elevated temperature
characteristics in a standard 6pin dual in line
plastic package.
FEATURES
zOptions :-
10mm lead spread - add G after part no.
Surface mount - add SM after part no.
T ape&reel - add SMT&R after part no.
zHigh Isolation V oltage (5.3kVRMS ,7.5kVPK )
zHigh Current Transfer Ratio ( 1000% min)
zHigh BVCEO (400V min. - IS662)
(300V min. - IS661)
(200V min. - IS660)
APPLICATIONS
zModems
zCopiers, facsimiles
zNumerical control machines
