bus termination
Product Description
Reflections on high speed data lines lead to undershoot and overshoot disturbances which may result in improper
system operation. Resistor terminations, when used to terminate high speed data lines, increase power consumption
and degrade output (high) levels resulting in reduced noise immunity. Schottky diode termination is the best overall
solution for applications in which power consumption and noise immunity are critical considerations.
This integrated Schottky diode network provides very effective termination performance for high speed data lines
under variable loading conditions. The device supports up to 12 terminated lines per package — each of which can
be simultaneously clamped to both ground and power supply rail.
