DESCRIPTION
The IS609 is an optically coupled isolator
consisting of a Gallium Arsenide infrared emitting
diode and a Microprocessor Compatible Schmitt
trigger output mounted in a standard 6 pin dual in
line package.
FEATURES

10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.
lHigh data rate, 1MHz typical (NRZ)
lMicroprocessor compatible drive
lLogic compatible output sinks 16
milliamperes at 0.4 volts maximum
lHigh Isolation Voltage (5.3kVRMS ,7.5kVPK )
lHigh common mode rejection ratio
lFast swiching : t rise, t fall = 100ns typical
lWide supply voltage capability, compatible
with all popular logic systems
lGuaranteed On / Off threshold hysteresis
APPLICATIONS
