MAX4885AE

19-5022; Rev 0; 10/09 TION KIT EVALUA BLE IL AVA A High-Bandwidth, VGA 2:1 Switch with ±15kV ESD Protection Features S Low 5I (typ) On-Resistance (R_, G_, B_ Signals) S Low 5.5pF (typ) On-Capacitance (R_, G_, B_ General Description The MAX4885AE integrates high-bandwidth analog switches, level-translating buffers, and level-translating FET switches to implement a complete 2:1 multiplexer for VGA signals. The device provides three very highfrequency 900MHz (typ) SPDT switches for RGB signals, two low-frequency clamping switches for the DDC signals, a pair of level-translating buffers for the H_ and V_ signals, and integrated extended ESD protection. Horizontal and vertical synchronization (H_/V_) inputs feature level-shifting buffers to support low-voltage controllers and standard 5V-TTL-compatible monitors, meeting the VESA requirement. Display Data Channel (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 seven output terminals of the MAX4885AE feature high-ESD protection to Q15kV Human Body Model (HBM) (see the Pin Description). All other pins are protected to Q2kV Human Body Model (HBM). The MAX4885AE is specified over the extended -40NC to +85NC temperature range, and is available in a spacesaving, 28-pin, 4mm x 4mm TQFN package.
