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.

Orders for the LOC211P product will be shipped using bins
available at the date of the order. Any bin can be shipped.
Part Number Information
The LOC211 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”.
