MAX14895E
Enhanced VGA Port Protector
General Description
The MAX14895E integrates level-translating buffers and
features RED, GRN, and BLU (RGB) port protection for
VGA signals.
The device has horizontal sync (SYNCH_) and vertical
sync (SYNCV_) translating buffers that convert low-level
CMOS inputs from a graphics controller to meet full 5V,
TTL-compatible outputs. Each output can drive Q 10mA
and meets the VESA SM specification. In addition, the
device translates the direct digital control (DDC) signals
to a lower level that is safe for the graphics controller.
The device features both EN and EN inputs, accepting
active-high or active-low enable inputs. The device also
switches and current limits the 5V supply to a VGA con-
nector or monitor.
The RED, GRN, and BLU terminals protect graphics con-
troller outputs against electrostatic discharge (ESD) events.
All eight outputs and EN have high-level ESD protection.
The MAX14895E is specified over the extended -40 N C to
+85 N C temperature range and is available in a 16-pin,
3mm x 3mm TQFN package with exposed pad.
