PI7AT04

SOTINY^TMLow Voltage, Zero-Delay,

Active Transmission Line Clamp

Features

Description

5V and 3.3V Line Clamping

Near Zero Quiescent Supply Current: 10µA Maximum

– Active circuit clamping

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.

Low Capacitance: 5pF (typ.)

High 4kV ESD Protection

Packaging (Pb-free & GreenAvailable):

- 6-pin SC70 (C)

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.

Benefits

Reduced EMI

– Limits high-frequency ring voltage

Minimum Power Consumption

Higher Noise Margin

Minimal Line Loading

Applications

The PI7AT04 does not replace parallel terminator resistors.
