SP3203

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 (CS ) are

15k

Ω and 100pF, respectively.
