Technical information
Frequency behavior of data and strobe signals
ESD protection
In addition to the requirements of termination and EMC compatibility, computing devices are
required to be tested for ESD susceptibility. This test is described in the IEC 61000-4-2 and
is already in place in Europe. This test requires that a device tolerates ESD events and
remain operational without user intervention.
The ST1284-01A8 is particularly optimized to perform ESD protection. ESD protection is
based on the use of device which clamps at:
V
This protection function is splitted in 2 stages. As shown in
clamped by the first stage S
stage through the resistor R. Such a configuration makes the voltage very low at the output.
