This device contains circuitry that protects the inputs against
damage due to high static voltages or electric field; however,
precautions should be taken to avoid application of any
voltage higher than the maximum rated voltages to this circuit.
For proper operation, VIN and VOUT should be constrained to
the range:
VSS < (VIN or VOUT) < VDD.
Unused inputs must always be tied to an appropriate logic
voltage level (either VSS or VDD).
Notes:
20. All outputs loaded per Table 7.
21. Applicable to input signals : SEL(0:1), PD# (pull-up).
22. Applicable to SDATA and SCLK.
23. Internal pull-up and pull-down resistors affect this current.
24. See Applications data that is presented later in this datasheet on crystal interfacing.
DC Parameters VDD = VDDS = 3.3V ± 5%, VDDC = VDDI = 2.5V ± 5%, TA = 0°C to +70°C
