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.
