The MAX4895E integrates level-translating buffers and

features R, G, B port protection for VGA signals.

The MAX4895E has H, V (horizontal, vertical) translat-

ing 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

+5.0V, direct digital control (DDC) signals and trans-

lates them to the lower level required by the graphics

device. This level is set by the user by connecting V

the graphics output supply. The R, G, B terminals pro-

tect the graphics output pins against electrostatic dis-

charge (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.
