Note 3: Tested at a single temperature. Specifications over temperature are guaranteed by design.
Note 4: MAX6629–MAX6632 are not specifically equipped with a shutdown function. Their low supply current permits powering
them from the output of a logic gate. This specification is given to ensure that the MAX6629–MAX6632 do not draw
excessive currents at low supply voltages, ensuring reliable operation from a gate output.
Note 5: Timing characteristics are guaranteed by design and are not production tested.
Note 6: C
LOAD = total capacitance of one bus line in picofarads.
