ESD4238 Application and Guidelines
As a general rule, the ESD4238 ESD protection array
should be located as close as possible to the point of entry of
expected electrostatic discharges with minimum PCB trace
lengths to the ground planes and between the signal input
and the ESD device to minimize stray series inductance.
