MAX14983E
Enhanced 1:2 VGA Mux with
Monitor Detection and Priority Port Logic
19-5935; Rev 0; 6/11
General Description
The MAX14983E integrates high-bandwidth analog
switches, level-translating buffers, and 5V power switches
to implement a complete 1:2 multiplexer for VGA moni-
tors. The device switches graphics signals between a
controller and two outputs. Integrated pullup resistors
(2.2kI typ) are provided on the monitor-side display data
channel (DDC) signal lines.
The device features a simple power interface that oper-
ates 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
Q
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 -40NC to +85NC
extended temperature range.
