Special Handling
of Static Sensitive
Devices
CMOS devices are designed to operate at very high impedance levels
for low power consumption. As a result, any normal static charge that
builds up on your person or clothing may be sufficient to destroy
these devices if they are not handled properly. When handling such
devices, use the precautions described below to avoid damaging
them:
1.
CMOS IC’s should be transported and handled only in con-
tainers specially designed to prevent static build-up. Typically,
these parts are received in static-protected containers of plas-
tic or foam. Keep these devices in their original containers un-
til ready for installation.
2. Ground yourself with a suitable wrist strap. Remove the de-
vices from the protective containers only at a properly
grounded workstation.
3. Remove a device by grasping the body; do not touch the
pins.
4. Any printed circuit board into which the device is to be insert-
ed must also be grounded to the bench or table.
5. Use only anti-static type solder sucker.
6. Use only grounded soldering irons.
Once the device is installed on the PC board, the device is
adequately protected and normal handling may resume.
