The MAX4895E integrates level-translating buffers and features R, G, B port protection for VGA signals.

The MAX4895E has H, V (horizontal, vertical) translating buffers that take low-level CMOS inputs from the graphics outputs to meet full +5.0V, TTL-compatible outputs. Each output can drive ±10mA and meet the VESA® specification. In addition, the device takes the +5.0V, direct digital control (DDC) signals and translates them to the lower level required by the graphics device. This level is set by the user by connecting V_L to the graphics output supply. The R, G, B terminals protect the graphics output pins against electrostatic discharge (ESD) events. All seven outputs have high-level ESD protection.

The MAX4895E is specified over the extended -40°C to +85°C temperature range, and is available in a 16-pin, 3mm x 3mm TQFN package.
