About SN74S1051,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 SN74S1051 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.
