This device is ideal for protecting systems with high data and clock rates or for circuits that require low capacitive loading. Each channel consists of a pair of ESD diodes that act as clamp diodes that steer positive or negative ESD current pulses to either the positive or negative supply rail. A zener diode is integrated into the array between the positive and negative supply rails. The VCC rail is thus protected from ESD strikes and eliminates the need for a bypass capacitor to absorb positive ESD strikes to ground. Each channel of the CM1230 can safely dissipate ESD strikes of ...
