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-volt-
age CMOS or standard TTL-compatible graphics con-
trollers, meeting the VESA requirement of ±8mA. DDC,
consisting of SDA_ and SCL_, is a bidirectional active-
level translating switch that reduces capacitive load. The
MAX4885E features high ESD protection to ±15kV
Human Body Model (HBM) on all twelve externally rout-
ed terminals. See the Pin Description section. All other
pins are protected to ±10kV Human Body Model (HBM).
The MAX4885E is specified over the extended -40°C to
+85°C temperature range, and is available in the
24-pin, 4mm x 4mm TQFN package.
