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.
