High-Bandwidth, VGA 2:1 Switch

with ±15kV ESD Protection

MAX4885AE

General Description

The MAX4885AE integrates high-bandwidth analog

switches, level-translating buffers, and level-translating

FET switches to implement a complete 2:1 multiplexer

for VGA signals. The device provides three very high-

frequency 900MHz (typ) SPDT switches for RGB signals,

two low-frequency clamping switches for the DDC sig-

nals, a pair of level-translating buffers for the H_ and V_

signals, and integrated extended ESD protection.

Horizontal and vertical synchronization (H_/V_) inputs

feature level-shifting buffers to support low-voltage

controllers and standard 5V-TTL-compatible monitors,

meeting the VESA requirement. Display Data Channel

(DDC), consisting of SDA_ and SCL_, are FET switches

that protect the low-voltage VGA source from potential

damage from high-voltage presence on the monitor

while reducing capacitive load.

All seven output terminals of the MAX4885AE feature

high-ESD protection to Q15kV Human Body Model

(HBM) (see the Pin Description). All other pins are pro-

tected to Q2kV Human Body Model (HBM).

The MAX4885AE is specified over the extended -40NC to

+85NC temperature range, and is available in a space-

saving, 28-pin, 4mm x 4mm TQFN package.
