PRODUCTION DATA
Although the SN65HVD178x-Q1 family of devices is internally protected against human-body-model ESD strikes up to 16kV, additional protection against higher-energy transients can be provided at the application level by implementing external protection devices.
Figure 8-4 shows a protection circuit intended to withstand 8kV IEC ESD (per IEC 61000-4-2) as well as 4kV EFT (per IEC 61000-4-4).
