CM1234 Application and Guidelines
As a general rule, the CM1234 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 sig-
nal input and the ESD device to minimize stray series inductance.
