19-0554; Rev 0; 5/06 EVALUATION KIT AVAILABLE Complete VGA 1:2 or 2:1 Multiplexer MAX4885 General Description Features The MAX4885 integrates high-bandwidth analog +5V Single-Supply Operation switches and level-translating buffers to implement acomplete 1:2 or 2:1 multiplexer for VGA signals. The Programmable Voltage Clamp for Open-Drain device provides switching for RGB, display data chan- DDC Signals nel (DDC), and horizontal and vertical synchronization Low 5 (typ) On-Resistance (R, G, B Signals) (HSYNC, VSYNC) signals. A low-noise charge pumpwith internal capacitors provides a boosted gate-drive Low 13pF (typ) On-Capacitance (R, G, B Signals) voltage to improve performance of the RGB switches.

In the ±8kV HBM ESD Protection on Externally Routed 2:1 multiplexer mode, the output buffers for the Pins HSYNC/VSYNC inputs are disabled, allowing bidirec- Low 300µA Supply Current (Lower than 1µA with tional signaling. In both modes, DDC signals are volt- Charge Pump Disabled) age-clamped to an external voltage to provide leveltranslation and protection. The MAX4885 features a Space-Saving, Lead-Free, 32-Pin (5mm x 5mm) 5µA shutdown mode and is ESD protected to ±8kV TQFN Package Human Body Model (HBM) on externally routed pins. The MAX4885 is specified over the extended (-40°C to+85°C) temperature range, and is available in the 32-pin, 5mm x 5mm TQFN package.
