Description
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 high-ESD protection to ±15kV Human Body Model (HBM) and ±6kV IEC 61000-4-2 Contact Discharge (see the Pin Description in the full data sheet). All other pins are protected to ±2kV HBM.
The MAX14885E is specified over the extended -40°C to +85°C temperature range, and is available in a 40-pin TQFN (5mm x 5mm) package.
