MAX4885E
19-4269; Rev 0; 10/08 EVAALVUAAILTAIOBNLEKIT
Ultra-Low Capacitance 1:2 VGA Switch with ±15kV ESD
General Description
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.
