Product Description

Reflections on high speed Memory Buses lead to undershoot and overshoot disturbances which may result in improper system operation. Resistor terminations, when used to terminate high speed memory or 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.
