ESD Protection
The MAX9257A/MAX9258A ESD tolerance is rated for
Human Body Model, Machine Model, IEC 61000-4-2
and ISO 10605. The ISO 10605 and IEC 61000-4-2
standards specify ESD tolerance for electronic sys tems.
LVDS outputs on the MAX9257A and LVDS inputs on
the MAX9258A meet ISO 10605 ESD protection and IEC
61000-4-2 ESD protection. All other pins meet the Human
Body Model and Machine Model ESD toler ances. The
Human Body Model discharge components are C
S
=
100pF and R
D
= 1.5kI (Figure 33). The IEC 61000-4-2
discharge components are C
S
= 150pF and R
D
= 330I
(Figure 32). The ISO 10605 discharge com ponents are
C
S
= 330pF and R
D
= 2kI (Figure 34). The Machine
Model discharge components are C
S
= 200pF and R
D
=
0I (Figure 35).
