PI7AT04

The PI7AT04 actively clamps overshoot and undershoot voltages on transmission lines and backplanes. Improperly terminated data lines have reflections that can result in lost data or unreliable system behavior.

The PI7AT04 clamps undershoot and overshoot voltages for up to four lines. For other options and packages contact Pericom Marketing.

Compared to Schottky diodes, the PI7AT04 uses less power and requires no additional drive power. By avoiding a passive termina-tion/clamp technology, PI7AT04 power consumption is very low at 5V.

The PI7AT04 is ideal in applications where characteristic imped-ance varies with system configuration. Changing characteristic impedance is common when memory or function cards are added or removed on a bus.

The PI7AT04 does not replace parallel terminator resistors.
