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 3: All typicals are given for VCC = 5V, C1 = C2 = C3 = 1F ceramic
capacitors and TA = 25°C.
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.
