Machine Model
The Machine Model for ESD testing uses a 200pF stor-
age capacitor and zero-discharge resistance. It mimics
the stress caused by handling during manufacturing
and assembly. Of course, all pins (not just RS-232
inputs and outputs) require this protection during man-
ufacturing. Therefore, the Machine Model is less rele-
vant to the I/O ports than are the Human Body Model
and IEC 1000-4-2.
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 into ground, so
be sure to minimize the ground-lead return path to the
power supply. A separate return path to the power sup-
ply is recommend. Trace widths should be greater than
40 mils. Bypass VCC, VDD, and VSS with 0.1F capaci-
tors as close to the part as possible to ensure maxi-
mum ESD protection.
Connect any unused transmitter inputs to GND or VCC.
The MAX3187 is not sensitive to power-supply
sequencing, and therefore requires no external protec-
tion diodes.
