is a stress rating only and functional operation of the device at those or any other conditions above those indicated in
the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods
may affect device reliability.
NOTICE: Stresses above those listed under “Maximum ratings” may cause permanent damage to the device. This

ELECTRICAL CHARACTERISTICS
Voltage spikes below V
Thus, a series resistor of 50 - 100Ω should be used when applying a “low” level to the RESET pin rather
than pulling this pin directly to V
