Fully Integrated VGA Port Protector Saves Space and Reduces Cost in Portable Applications
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 synch (SYNCV_) translating buffers that convert low-level CMOS inputs from a graphics controller to meet full 5V, TTL-compatible outputs. Each output can drive ±10mA and meets the VESASM 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 active-low EN inputs, accepting active-high or active-low enable inputs. The device also switches and current limits the 5V supply to a VGA connector or monitor. The RED, GRN, and BLU terminals protect graphics controller outputs against electrostatic discharge (ESD) events. All eight outputs and active-low EN have high-level ESD protection. The MAX14895E is specified over the extended -40°C to +85°C temperature range and is available in a 16-pin, 3mm x 3mm TQFN package with exposed pad.
