HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is desirable to take
precautions appropriate to handling MOS devices. Advice can be found in Data Handbook IC24 under ”Handling MOS devices”.
DC CHARACTERISTICS
VDD = 3.0 to 3.6 V; VSS = 0 V; Tamb = 0 to +70 °C; unless otherwise specified.
