Product data sheet
The NX5DV713 provides the level shifting necessary to drive two standard VGA ports
from a graphic controller as low as 2.2 V. Internal buffers drive the HSYNC and VSYNC
signals to VGA standard TTL levels. The DDC multiplexer provides level shifting by
clamping signals to a diode drop less than V
for normal operation, or to V
