Diode Network / ESD Suppressor COMCHIP www.comchiptech.com CDA4S14L Voltage: 8 Volts Current: 50 mA Package (SOT-143) Feature Marking “ CDA4 “ This diode network is designed to provide two channels for active termination of highspeed data signals to eliminate signal undershoot and overshoot. The network has the added benefit of acting to suppress any ESD voltage events by shunting the energy to ground assuring maximum reliability of electronic systems in the field. Trigger levels are defined by the positive and negative bias levels set by the user. Schematic 4 3 1 2 Application ESD Driver Positive Supply Receiver Neg. Supply or Gnd.
