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 4: Channel-to-Channel Skew is defined as the difference between the propagation delay of the channel and the other channels in the same chip with an event

on the inputs.

Note 5: Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays.

Note 7: ESD Ratings:

HBM (1.5 k

Ω, 100 pF) ≥ 2kV

EIAJ (0

Ω, 200 pF) ≥ 250V
