A single-chip VGA port protector IC for PC-based applications

Maxim has introduced the MAX4895E, a VGA port protector IC that features an interface between a video graphics controller and VGA port connector. This MAX4895E integrates HSYNC/VSYNC level-shifting buffers to support VESA VSIS specifications, and includes robust ESD protection on all seven VGA video outputs that eliminates the need for the multiple analog and passive components required by discrete implementations. The MAX4895E is suitable for notebook PCs, desktop computers, servers, and consumer video applications.

The MAX4895E operates from a single +5.0V supply and integrates level-shifting buffers to support low-voltage CMOS or standard TTL-compatible graphics controllers, and also features I²C level shifting using two nMOS devices. All video outputs are characterized for ±15kV (Human Body Model) and ±8kV (IEC 61000-4-2 Contact Discharge) ESD protection. The device features low capacitance (3pF, max) on the RGB terminals, and low quiescent current (5µA, max) for high-bandwidth applications.

Operating temperature range: -40°C to +85°C
Package: 3mm x 3mm, 16-pin TQFN
Price: Starts at $0.68 for 1k pieces
