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, V
IN
and V
OUT
should be constrained to
the range:
V
SS
< (V
IN
or V
OUT
) < V
DD
.
Unused inputs must always be tied to an appropriate logic
voltage level (either V
SS
or V
DD
).
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.
