Maxim Integrated MAX14885E

The MAX14885E integrates high-bandwidth analog switches, level-translating buffers, and level-translating FET switches. The device implements a complete 2:2 dual-graphics crossover solution for VGA signal switching. The MAX14885E provides 12 very high-frequency 700MHz (typ) SPST switches for RGB signals, four lowfrequency clamping switches for display data channel (DDC) signals, two pairs of level-translating buffers for the HSYNC and VSYNC signals, and integrated extended ESD protection.

GENERAL DESCRIPTION

The MAX14885E is used to select one of two sources to either of two destinations (see the Typical Operating Circuit) within a laptop computer. Horizontal and vertical synchronization (SH_/SV_) inputs feature level-shifting buffers to support low-voltage controllers and standard 5V TTL-level monitors. DDC, consisting of SDA_ and SCL_, are FET switches that protect the low-voltage VGA source from potential damage from high-voltage presence on the monitor while reducing capacitive load. All 14 output terminals of the MAX14885E feature highESD protection to Q15kV Human Body Model (HBM) and Q6kV IEC 61000-4-2 Contact Discharge (see the Pin

DESCRIPTION

). All other pins are protected to Q2kV HBM. The MAX14885E is specified over the extended -40NC to +85NC temperature range, and is available in a 40-pin TQFN (5mm x 5mm) package.
