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 unless otherwise
specified (such as V
ID
).
Note 3:
All typicals are given for: V
DD
= +3.3V and T
A
= +25°C.

Note 5:
Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted at a time, do not
exceed maximum junction temperature specification.
Note 6:
C

includes probe and jig capacitance.
Note 7:

O

(0% to 100%)
≤
3 ns for IN±.
Note 8:
t
SKD1
is the magnitude difference in differential propagation delay time between the positive-going-edge and the negative-going-edge of the same channel.
Note 9:
t
SKD3
, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same
V
DD
and within 5°C of each other within the operating temperature range.
Note 10:
t
SKD4
, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over the
recommended operating temperature and voltage ranges, and across process distribution. t
SKD4
is defined as |Max − Min| differential propagation delay.
Note 11:
V

is always higher than IN+ and IN− voltage. IN+ and IN− are allowed to have voltage range −0.05V to +2.35V when V

cycle, V
OL

OH
(min 2.4V), load = 15 pF (stray plus probes). The parameter is guaranteed by design. The limit is based on the statistical analysis of
the device over the PVT range by the transition times (t

and t
THL
).
