MAX14895E

Enhanced VGA Port Protector

General Description

Benefits and Features

The MAX14895E integrates level-translating buffers and

features RED, GRN, and BLU (RGB) port protection for

VGA signals.

S Saves Power in Portable Applications

ꢀLow Quiescent Supply Current: 430µA (typ)

S Eliminates Need for Costly External Components

 High-ESD Protection on SDA1, SCL1, SYNCH1,

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 Q10mA

and meets the VESA^SMspecification. In addition, the

device translates the direct digital control (DDC) signals

to a lower level that is safe for the graphics controller.

SYNCV1, RED, GRN, BLU, EN, V

 ±1ꢀ5V Human Body Model (HBM)

 ±±5V IEC 61000-4-2 Contact Discharge

S Innovative Design Enables a High Level of

Integration for Performance

 Output Current-Limit Switch with Power-Off

Protection

 Low Capacitance on RGB Ports (2.2pF typ)

 10mA Drive on SYNCH1, SYNCV1

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.

S Fully Integrated Solutions Saves Space in Portable

Applications

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.

 DDC Outputs have Internal Pullups

 3mm x 3mm, 16-Pin TQFN Pac5age

The MAX14895E is specified over the extended -40NC to

+85NC temperature range and is available in a 16-pin,

3mm x 3mm TQFN package with exposed pad.
