Application Information

Precautions to Avoid Permanent Device Damage:

Static Sensitivity: Follow ESD precautions to protect against ESD damage.

• A properly grounded static-dissipative surface on which to place devices.

• Static-dissipative floor or mat.

• A properly grounded conductive wrist strap for each person to wear while handling devices.
