Product Pin Description
Description
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.
