Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2:
Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except differential volt-

Note 6:
See TIA/EIA-422-B specifications for exact test conditions.
Note 7:
This specification limit is for compliance with TIA/EIA-422-B and ITU-T V.11.
Note 8:
Devices are at the same V
CC
and within 5˚C within the operating temperature range
Note 9:
All channels switching, output duty cycle criteria is 40%/60% measured at 50%. This parameter is guaranteed by design and characterization.
Note 10:
This parameter does not meet the TIA/EIA-422-B specification.
