SP3220EB/EU +3.0 to +5.0V RS-232 Transceivers

For the Human Body Model, the current

limiting resistor (R

S) and the source capacitor

S) are 1.5k

and 100pF, respectively. For

IEC-1000-4-2, the current limiting resistor (RS)

and the source capacitor (CS) are 330 and

150pF, respectively.

The higher CS value and lower RS value in the

IEC1000-4-2 model are more stringent than the

Human Body Model. The larger storage capaci-

tor injects a higher voltage to the test point when

SW2 is switched on. The lower current limiting

resistor increases the current charge onto the test

point.
