CDA 4S14 L
Voltage: 8 Volts Current: 50 m A
Package (SOT-143)
Feature
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.
