infrared LED optically coupled with two phototransis-
tors. One feedback (input) phototransistor is used to
generate a control signal that provides a servomech-
anism to the LED drive current, thus compensating
for the LEDs nonlinear time and temperature charac-
teristics. The other (output) phototransistor provides
an output signal that is linear with respect to the
servo LED current. The product features wide band-
width, high input to output isolation and excellent
servo linearity.

Part Number Information
The LOC210 are shipped in anti-static tubes (50
pieces each) or tape/reel (1,000 pieces each). Each
container has only 1 bin combination which will be
branded on each part with the appropriate bin letter
K, L, M, or N in the lower right hand corner. Suffix
representation is described in the “Bin Matrix”.

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 these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure
of the device to the absolute maximum ratings for an
extended period may degrade the device and effect its
reliability.
