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 device
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 V
OD
and ∆ V
OD
.
Note 3: All typical are given for V
CC
= +3.3V and T
A
= +25˚C, unless otherwise stated.
Note 4: Output short circuit current (I OS ) is specified as magnitude only, minus sign indicates direction only.
Note 5: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over the PVT (process, voltage and
temperature) range.
Note 6: t

|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of
the same channel.
Note 7: t
SKD3
, Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification
applies to devices at the same V
CC
and within 5˚C of each other within the operating temperature range.
Note 8: t
SKD4
, Part to Part Skew, is the differential channel-to- channel skew of any event between devices. This specification applies to devices over recommended
operating temperature and voltage ranges, and across process distribution. t
SKD4
is defined as |Max − Min| differential propagation delay.
Note 9: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over the PVT range with the following test
equipment setup: HP8133A (pattern pulse generator), 5 feet of RG142B cable with DUT test board and HP83480A (digital scope mainframe) with HP83484A (50GHz
scope module). The HP8133A with RG142B cable exhibit a t
DJ
= 21ps and t
RJ
= 1.8ps.
