The SY88822V is a high speed current switch for driving
a semiconductor laser diode in optical transmission
applications. The modulation current (I OUT ) is controlled by
the current (I RSET ) through the external resistor R SET . The
output OUT is HIGH and no current flows through OUT
when output enable is HIGH.
The device incorporates complementary open collector
outputs with a 30mA maximum current driving capability.
The external resistor R EXT must be placed between /OUT
and V CC to dissipate the worst case power. R SER is
recommended to compensate for laser diode matching

issues. Pin 9 and pin 10 should be connected to achieve
better performance.
The SY88822V utilizes the high performance bipolar
ASSET? technology.
