DESCRIPTION
The IS4N45, IS4N46 are optically coupled
isolators consisting of an infrared light emitting
diode and a 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. These devices are designed to
equal the 4N45, 4N46 characteristics while
providing greater voltage and current capability.
FEATURES
lOptions :-
10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.
lHigh Isolation Voltage (5.3kVRMS ,7.5kVPK )
lHigh Current Transfer Ratio ( 1500% typ.)
lHigh BVCEO ( 55V min.)
lInternal base-emitter resistor minimizes
output leakage
lLow input current 0.5mA IF
APPLICATIONS
lTelephone ring detector
lDigital logic ground isolation
lLow input current line receiver
lLogic to reed relay interface
lLevel shifting
lInterface between logic families
lLine voltage status indicator - low input
