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 = 2.3 to 5.5 V; VSS = 0 V; Tamb = -40 to +85 °C; unless otherwise specified. TYP at 3.3 V and 25 °C.
