DN5
diode terminator network
This diode network is designed to provide nineteen
channels of active termination for high-speed 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.
