General Description
The MAX4885 integrates high-bandwidth analog
switches and level-translating buffers to implement a
complete 1:2 or 2:1 multiplexer for VGA signals. The
device provides switching for RGB, display data chan-
nel (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.
In the 1:2 multiplexer mode, HSYNC/VSYNC inputs fea-
ture level-shifting buffers to support low-voltage CMOS
or standard TTL-compatible graphics controllers. In the
2:1 multiplexer mode, the output buffers for the
HSYNC/VSYNC inputs are disabled, allowing bidirec-
tional signaling. In both modes, DDC signals are volt-
age-clamped to an external voltage to provide level
translation and protection. The MAX4885 features a
5A shutdown mode and is ESD protected to ±8kV
Human Body Model (HBM) on externally routed pins.
The MAX4885 is specified over the extended (-40°C to
+85°C) temperature range, and is available in the 32-
pin, 5mm x 5mm TQFN package.
