High-Bandwidth, VGA 2:1 Switch

with 1ꢀ5V ESD Protection

General Description

Features

S Low 5I (typ) On-Resistance (R_, G_, B_ Signals)

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.

S Low 5.5pF (typ) On-Capacitance (R_, G_, B_

Signals)

S Independent, Selectable Logic Inputs for

Switching

S Similar Pin Configuration to MAX4885

S Ultra-Small, 28-Pin (4mm x 4mm) TQFN Package

S Q15kV ESD HBM

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.
