Triple Video Switch

General Description

Features

The MAX4887 triple, high-frequency switch is intended

for notebooks and monitors to permit RGB signals to be

switched from one driver to one of two loads (1:2) or one

of two sources to be connected to one load (2:1). The

MAX4887 high-performance switch utilizes n-channel

architecture with internal high-drive pullup from a low-

noise charge pump, resulting in very low on-capacitance.

♦ +3V/+5V Single-Supply Operation

♦ Low R

(V+ = 5V)

♦ Low 10pF (typ) C

♦ Global ENABLE Input to Turn On/Off Switches

♦ Break-Before-Make Switching

The MAX4887 features 5 (typ) on-resistance switches

with 10pF on-capacitances for routing RGB video sig-

nals. A logic input enables or disables the internal

charge pump for optimal frequency performances when

operating at lower input voltages resulting in standby

supply current less than 3µA. All RGB inputs/outputs are

ESD protected to 8kꢀ ꢁuman Body Model (ꢁBM) and

feature a global input (EN) that places all inputs and out-

puts in a high-impedance state.

♦ ±±kV ꢀBM ESꢁ ꢂrotection per IEC1000-ꢃ-ꢄ on I/Os

♦ Less than 1mA Supply Current (Charge ꢂump

Enabled)

♦ Less than 3µA Standby Mode

♦ Charge-ꢂump Noise Lower than 163µV

ꢂ-ꢂ

♦ Flowthrough Layout for Easy Board Layout

The MAX4887 is available in a small 3mm x 3mm, 16-

pin TQFN package for ease of assembly and

flowthrough layout, resulting in minimum space require-

ment and simplicity in board layout. The MAX4887

operates over the -40°C to +85°C temperature range.
