LTC1345

Note 1: The absolute maximum ratings are those values beyond which the

safety of the device cannot be guaranteed.

Note 2: All currents into device pins are termed positive; all currents out of

device pins are termed negative. All voltages are referenced to device

ground unless otherwise specified.

Note 4: Maximum data rate is specified for NRZ data encoding scheme.

The maximum data rate may be different for other data encoding schemes.

Data rate is guaranteed by correlation and is not tested.
