Note

1. Stress above those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device. This is

a stress ratings only and functional operation of the device at these or any other conditions above those indicated in

the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.

9 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 IC12 under

“Handling MOS Devices”.

10 CHARACTERISTICS

VDD = 2.5 to 5.5 V; VSS = 0 V; Tamb = −40 to +85 °C; unless otherwise specified.
