1. V
2. Typical values reflect average measurements at midpoint of voltage range, 25 C only.
3. Values are based on characterization results, not tested in production.
4. All functional non-supply pins are internally clamped to V
5. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
6. Power supply must maintain regulation within operating V
7. If minimum V

present, or if clock rate is very low (which would reduce overall power consumption).
