ESD TOLERANCE
The SP3203 incorporates ruggedized ESD cells
on all driver output and receiver input pins.
The Human Body Model has been the generally
accepted ESD testing method for semiconductors.
This method is also specified in MIL-STD-883,
Method 3015.7 for ESD testing. The premise of
this ESD test is to simulate the human body’s
potential to store electro-static energy and
discharge it to an integrated circuit. The
simulation is performed by using a test model as
shown in Figure 18. This method will test the
IC’s capability to withstand an ESD transient
during normal handling such as in manufacturing
areas where the ICs tend to be handled frequently.
For the Human Body Model, the current limiting
resistor (R_S) and the source capacitor (C_S ) are
15kΩ and 100pF, respectively.
