19-5819 Rev 0 3/11 E V A L U A T I O N K I T A V A I L A B L E MAX14895E Enhanced VGA Port Protector General Description Benefits and Features The MAX14895E integrates level-translating buffers and S Saves Power in Portable Applications features RED, GRN, and BLU (RGB) port protection for Low Quiescent Supply Current: 430A (typ) VGA signals. S Eliminates Need for Costly External Components The device has horizontal sync (SYNCH ) and vertical High-ESD Protection on SDA1, SCL1, SYNCH1, sync (SYNCV ) translating buffers that convert low-level SYNCV1, RED, GRN, BLU, EN, V S CMOS inputs from a graphics controller to meet full 5V, 15kV Human Body Model (HBM) TTL-compatible outputs. Each output can drive Q10mA 8kV IEC 61000-4-2 Contact Discharge SM and meets the VESA specification. In addition, the S Innovative Design Enables a High Level of device translates the direct digital control (DDC) signals Integration for Performance to a lower level that is safe for the graphics controller. Output Current-Limit Switch with Power-Off The device features both EN and EN inputs, accepting Protection active-high or active-low enable inputs. The device also Low Capacitance on RGB Ports (2.2pF typ) switches and current limits the 5V supply to a VGA con- 10mA Drive on SYNCH1, SYNCV1 nector or monitor. S Fully Integrated Solutions Saves Space in Portable The RED, GRN, and BLU terminals protect graphics con- Applications troller outputs against electrostatic discharge (ESD) events. DDC Outputs have Internal Pullups All eight outputs and EN have high-level ESD protection. 3mm x 3mm, 16-Pin TQFN Package The MAX14895E is specified over the extended -40NC to +85NC temperature range and is available in a 16-pin, Ordering Information appears at end of data sheet. 3mm x 3mm TQFN package with exposed pad.
