The LOC110 Single Linear Optocoupler features an
infrared LED optically coupled with two
phototransistors. One feedback (input)
phototransistor is used to generate a control signal
that provides a servomechanism to the LED drive
current, thus compensating for the LEDs nonlinear
time and temperature characteristics. The other
(output) phototransistor provides an output signal that
is linear with respect to the servo LED current. The
product features wide bandwidth, high input to output
isolation and excellent servo linearity.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
