产品描述:
Enhanced 1:2 VGA Mux with Monitor Detection and Priority Port LogicInnovative Design Allows for New Monitor Selection to Operate Autonomously
The MAX14983E integrates high-bandwidth analog switches, level-translating buffers, and 5V power switches to implement a complete 1:2 multiplexer for VGA monitors. The device switches graphics signals between a controller and two outputs. Integrated pullup resistors (2.2kΩ typ) are provided on the monitor-side display data channel (DDC) signal lines.
The device features a simple power interface that operates with a single +5V supply input. Two integrated power switches with current limiting and reverse-current protection pass the +5V supply to external loads with minimal voltage drop.
The horizontal and vertical synchronization (HSYNC/VSYNC) buffers shift logic levels to support +2.5V to +5.0V CMOS or TTL-compatible graphics controllers while meeting the VESA drive capability requirement of ±8mA. An internal 2.5V regulator translates the DDC voltage levels to be compatible with low-voltage graphics controllers.
The device also features monitor-detect outputs and enable inputs that allow monitor switching to operate either automatically or with inputs from the graphics controller. The MAX14983E is available in a 32-pin (5mm x 5mm) TQFN package, and is specified over the -40°C to +85°C extended temperature range.
