= -55°C to +125°C, unless otherwise noted. Typical values are at V
CC
= +3.3V and T
A
= +25°C.) (Notes
2 and 3)
Note 2: Tested at a single temperature. Specifications over temperature are guaranteed by design.
Note 3: The 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 exces-
sive currents at low supply voltages, ensuring reliable operation from a gate output.
Note 4: Timing characteristics are guaranteed by design and are not production tested.
Note 5: C
LOAD
= total capacitance of one bus line in picofarads.
