NOTE:
Electrostatic Discharge (ESD) Precautions
The following practices minimize possible damage to ICs
resulting from electrostatic discharge or improper inser-
tion.
• Keep parts in original containers until ready for use.
• Avoid having plastic, vinyl or styrofoam in the work
area.
•. Wear an anti-static wrist-strap.
• Discharge personal static before handling devices.
• Remove and insert boards with care.
• When removing boards, handle only by non-conduc-
tive surfaces and never touch open-edge connectors
except at a static-free workstation.*
• Minimize handling of ICs.
•. Handle each IC by its body.
• Do not slide ICs or boards over any surface.
• Insert ICs with the proper orientation, and watch for
bent pins on ICs.
• Use anti-static containers for handling and transport.
*To make a plastic-laminated workbench anti-static, wash with
a solution of liquid detergent, and allow to dry without rinsing.
