DESCRIPTION
The IS6091 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
l Options :-
10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.
l High data rate, 1MHz typical (NRZ)
l Microprocessor compatible drive
l Logic compatible output sinks 16
milliamperes at 0.4 volts maximum
l High Isolation Voltage (5.3kV
RMS
,7.5kV
PK
)
l High common mode rejection ratio
l Fast swiching : t rise, t fall = 100ns typical
l Wide supply voltage capability, compatible
with all popular logic systems
l Guaranteed On / Off threshold hysteresis
APPLICATIONS
l Logic to logic isolator
l Line receiver-eliminates noise and
transient problems
