Absolute Maximum Ratings are stress ratings. Functional
operation of the device at these or any other conditions
beyond those indicated in the operational 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.

The LOC110/LOC111/LOC112 are shipped in anti-static tubes of 50
pieces. Each tube will contain one K3 sorted bin.
Bin designation marked on each device (A-J).
Orders for the LOC110 product will be shipped using bins available at
the date of the order. Any bin (A-J) can be shipped.
For customers requiring selected bins D E F G we offer part numbers LOC111 or LOC112.
