1. Permanent damage can occur if maximum ratings are exceeded. Exposure to voltages or
currents in excess of recommended values affects device reliability. Device modules may
not operate normally while being exposed to electrical extremes.
2. Although sections of the device contain circuitry to protect against damage from high static
voltages or electrical fields, take normal precautions to avoid exposure to voltages higher
than maximum-rated voltages.
3. All pins except
/TSC
TSTME
4. All functional non-supply pins are internally clamped to V . All functional pins except EX-
SS
TAL and XFC are internally clamped to V
.
DD
5. Input must be current limited to the value specified. To determine the value of the required
current-limiting resistor, calculate resistance values for positive and negative clamp voltag-
es, then use the larger of the two values.
6. Power supply must maintain regulation within operating V range during instantaneous and
DD
operating maximum current conditions.
7. This parameter is periodically sampled rather than 100% tested.
8. Total input current for all digital input-only and all digital input/output pins must not exceed
10 mA. Exceeding this limit can cause disruption of normal operation.
