MAX4885 Overview
The MAX4885 integrates high-bandwidth analog switches and level-translating buffers to implement a plete 1:2 or 2:1 multiplexer for VGA signals. The device provides switching for RGB, display data channel (DDC), and horizontal and vertical synchronization (HSYNC, VSYNC) signals. A low-noise charge pump with internal capacitors provides a boosted gate-drive voltage to improve performance of the RGB switches.
MAX4885 Key Features
- +5V Single-Supply Operation
