The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. It does not spe-
cifically refer to integrated circuits. The major difference
between tests done using the HBM and IEC 61000-4-2
is higher peak current in IEC 61000-4-2, because series
resistance is lower in the IEC 61000-4-2 model. Hence,
the ESD withstand voltage measured to IEC 61000-4-2
is generally lower than that measured using the HBM.
Figure 6
shows the current waveform for the Q8kV, IEC 61000-4-2,
Level 4, ESD Contact-Discharge Method.
Hi-Speed USB requires careful PCB layout with 45I
single-ended/90I differential controlled-impedance
matched traces of equal lengths. Ensure that bypass
capacitors are as close to the device as possible. Use
large ground planes where possible.
Note: All devices are specified over the -40°C to +85°C tem-
perature range.
