General Description

The PACVGA105 incorporates 7 channels of ESD protection for signal lines commonly found in a VGA port for PCs.

ESD protection is implemented with current steering diodes designed to safely handle the high peak surge currents associated with the IEC-1000-4-2 Level-4 ESD Protection Standard (8kV contact discharge).

When the channels are subjected to an electrostatic discharge, the ESD current pulse is diverted via the protection diodes into the positive supply rails or ground where they may be safely dissipated.

Overview

PACVGA105 VGA Port Companion Circuit.

Key Features

7 channels of ESD protection designed to meet IEC-1000-4-2 Level-4 ESD requirements (8kV contact discharge) Very low loading capacitance from ESD protection diodes at less than 5pF typical TTL to CMOS level-translating buffers for the HSYNC and VSYNC lines Three independent supply pins (VCC, VRGB and VAUX) to facilitate operation with sub-micron Graphics Controller ICs High impedance pull-ups (50kΩ nominal to VAUX) for HSYNC and VSYNC inputs Pull-up resistors (1.8kΩ nominal to VCC) for.
