Please note that the EMIF02-600FU7 is not only acting for positive ESD surges but also for negative ones. For these kind

of disturbances it clamps close to ground voltage as shown in Fig. A5b.

NOTE: DYNAMIC RESISTANCE MEASUREMENT

As the value of the dynamic resistance remains stable for a

surge duration lower than 20

µs, the 2.5µs rectangular surge

is well adapted. In addition both rise and fall times are

optimized to avoid any parasitic phenomenon during the

measurement of Rd.

CROSSTALK BEHAVIOR

1- Crosstalk phenomena

The crosstalk phenomena are due to the coupling between 2 lines. The coupling factor (

fact the real voltage at this point has got an extra value

crosstalk phenomenon of the line 1 on the line 2. This phenomenon has to be taken into account when the drivers impose

fast digital data or high frequency analog signals in the disturbing line. The perturbed line will be more affected if it works

with low voltage signal or high load impedance (few k

Ω). The following chapters give the value of both digital and analog

crosstalk.
