17 LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 34); see notes 1 and 2.

Notes

1. Stresses above those listed under Limiting Values may cause permanent damage to the device.

2. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to

18 HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However it is good practice to take

normal precautions appropriate to handling MOS devices (see

“Handling MOS devices”).
