2:1 VGA multiplexer IC for notebook and consumer video applications

Maxim Integrated Products has introduced the MAX4885AE, a complete 2:1 VGA multiplexer. This device can be used to switch two VGA signals from a graphics controller to one connector while maintaining a low 5.5pf (typ) on-capacitance for higher bandwidth applications operating up to 900MHz. The MAX4885AE is ideal for use in notebook PCs, servers, and consumer video applications.

Maxim says the MAX4885AE is the only 2:1 switch offering a complete VGA solution with two separate control signals that independently switch between the high-frequency and low-frequency circuitry. This device provides glitch-free switching and two times more bandwidth than any existing solution.

This device integrates ±15kV (HBM) and ±8kV (IEC 61000-4-2 Contact Discharge) ESD protection to eliminate external protection diodes. The integrated switching architecture and ESD protection feature offer cost and space advantage.

The MAX4885AE operates from a single 5.0V supply, and is fully specified over the -40°C to +85°C extended temperature range. It is available in an industry-standard, 4mm x 4mm, 28-pin TQFN package. Pricing starts at $2.50 (1000-up, FOB USA).
