Note:
Stresses greater than those listed under Absolute Maximum Ratings may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above
those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended

Notes:
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.
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.
2.
3.
4.
5.
All typicals are given for: VCC = +3.3V, TA = +25°C.
Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50Ω, tR and tF (0% to 100%) ≤ 3ns for RIN
The VCMR range is reduced for larger VID. Example : if VID = 400mV, the VCMR is 0.2V to 2.2V. The fail-safe condition with inputs
shorted is valid over a common-mode range of 0V to 2.3V. A VID up tp VCC - 0V may be applied to the RIN+ / RIN- inputs with the
Common-Mode voltage set to VCC/2. Propagation delay and Differential Pulse skew decrease when VID is increased from 200mV to
400mV. Skew specifications apply for 200mV ≤ VID ≤ 800mV over the common mode range.

tskd1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the
samechannel.
t
SKD2, Channel-to-Channel Skew, is defined as the difference between the propagation delay of one channel and that of the others on the
same chip with any event on the inputs.
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 VCC,and within 5ºC of each other within the operating temperature range.
SKD4, Part-to-Part Skew, is the differential Channel-to-Channel skew of any event between devices. This specification applies
t
t
to devices over recommended operating temperature and voltage ranges, and across process distribution. tskd4 is defined as IMax - Mini
differential propagation delay.
10. Output short circuit current (IOS) 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.
11. CL includes probe and jig capacitance.
12.
V
CC is always higher than RIN+ and RIN- voltage. RIN- and RIN+ are allowed to have a voltage range -0.2V to VCC- VID/2.
However, to be compliant with AC specifications, the common voltage range 0.1V to 2.3V.
13. fmax generator input conditions: tR = tF < 1ns, (0% to 100%), 50% duty cycle, differential (1.05V to1.35V peak to peak).
Output Criteria: duty cycle = 60%/40%, VOL (max 0.4V), VOH (min 2.7V), Load = 10pF (stray plus probes).
