The MAX4885E integrates high-bandwidth analog switches and level-translating buffers to implement a complete 1:2 multiplexer for VGA signals. The device provides switching for RGB, display data channel (DDC). Horizontal and vertical synchronization (HSYNC/VSYNC) inputs feature level-shifting buffers to support low-voltage CMOS or standard TTL-compatible graphics controllers, meeting the VESA requirement of 8mA. DDC, consisting of SDA_ and SCL_, is a bidirectional activelevel translating switch that reduces capacitive load. The MAX4885E features high ESD protection to 15kV Human Body Model (HBM) on all twelve externally routed terminals. See the Pin Description section. All other pins are protected to 10kV Human Body Model (HBM). The MAX4885E is specified over the extended -40C to +85C temperature range, and is available in the 24-pin, 4mm x 4mm TQFN package. |
