Some designers prefer to use a “rail-to-rail” clamping technique for ESD protection and Bourns® can satisfy this scheme with discrete or array Schottky diode solutions. Using the V_CC line as positive and the Gnd, or V_DD, line as negative, ESD transients on data-lines can be diverted to either the positive or negative rail. A range of Schottky/Steering diodes are available in discrete and array SMT packages that would be ideal for this application.
