DESCRIPTION

The

AZC399 is a 4 channel ultra low capacitance rail

protection diodes array. Each channel consists of

diodes that steer positive or negative ESD current

positive or negative rail. A zener diode is integrated

between the positive and negative suppl y rails.

In the typical applications, the negative rail pin

(assigned as is connected with system

ground. The Positive ESD current is steered to the

ground through an ESD diode and Zener diode and

the

positive ESD voltage is clamped to t he zener

volta ge.

The

AZC399 is idea to protect high speed data lines.

package type is provided for easy PCB layout.

The

AZC399 is available in TSO T 26 p a ckage
