Machine Model
The Machine Model for ESD testing uses a 200pF stor-
age capacitor and zero-discharge resistance. Its objec-
tive is to mimic the stress caused by contact that
occurs with handling and assembly during manufactur-
ing. Of course, all pins (not just RS-232 inputs and out-
puts) require this protection during manufacturing.
Therefore, the Machine Model is less relevant to the I/O
ports than the Human Body Model and IEC1000-4-2.
__________ Applications Information
Use proper layout to ensure other devices on your
board are not damaged in an ESD strike. Currents as
high as 60A can instantaneously pass through the
ground pin, so it is important to minimize the ground-
lead return path to the power supply. A separate return
path to the power supply is recommended. Trace
widths should be greater than 40 mils. VCC must be
bypassed with 0.1F capacitors as close to the part as
possible to ensure maximum ESD protection.
