APPLICATION NOTES

5.1

ESD Performance

The USB3740B is protected from ESD strikes. By eliminating the requirement for external ESD protection devices,

board space is conserved, and the board manufacturer is enabled to reduce cost. The advanced ESD structures inte-

grated into the USB3740B protect the device whether or not it is powered up.

5.1.1

HUMAN BODY MODEL (HBM) PERFORMANCE

HBM testing verifies the ability to withstand the ESD strikes like those that occur during handling and manufacturing,

and is done without power applied to the IC. To pass the test, the device must have no change in operation or perfor-

mance due to the event. The USB3740B HBM performance is detailed in Table 3-1.
