1.4 Electrostatic Discharge (ESD) Protection Circuitry
provides a composite view of the ESD domains showing the ESD protection paths between each pad and the
substrate (GND), as well as the interrelations between some domains. Note that this figure represents the structure for the
internal protection devices and that additional protections can be implemented as part of the integration into the board.
Figure 1-3. Composite ESD Topology
shows the individual ESD domains and lists the pins associated with each domain.
ESD-sensitive device. The CS4399 is manufactured on a CMOS process. Therefore, it is generically
susceptible to damage from excessive static voltages. Proper ESD precautions must be taken while
handling and storing this device. This device is qualified to current JEDEC ESD standards.
