DS9502 Datasheet (Dallas Semiconducotr)

DS9502, ESD Protection Diode

This DS9502 was designed as an additional ESD protection for SRAM *based battery *buffered portable memory modules.

The memory chips used for these modules have already a strong ESD *protection structure on their I/O line.

Together with the DS9502 the ESD protection level is rai
