Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
except V
TH
and V
TL
.
Note 2:
Maximum and minimum limits overtemperature are guaranteed by design and characterization. Devices are production
tested at T
A

Note 3:
AC parameters are guaranteed by design and characterization, and are not production tested. Limits are set at ±6 sigma.
Note 4:

includes probe and test jig capacitance.
Note 5:
RCIP is the period of RxCLK IN. RCOP is the period of RxCLK OUT. RCIP = RCOP.
