General Description
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 lownoise charge pump, resulting in very low on-capacitance.
The MAX4887 features 5Ω (typ) on-resistance switches
with 10pF on-capacitances for routing RGB video signals. 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 ±8kV Human Body Model (HBM) and
feature a global input (EN) that places all inputs and outputs in a high-impedance state.
The MAX4887 is available in a small 3mm x 3mm, 16pin TQFN package for ease of assembly and
flowthrough layout, resulting in minimum space requirement and simplicity in board layout. The MAX4887
operates over the -40°C to +85°C temperature range.

Detailed Description
The MAX4887 triple, high-frequency switch is intended
for notebooks and monitors permitting RGB (red,
green, blue) 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 provides three
SPDT high-bandwidth switches to route standard VGA
R, G, and B signals (see Table 1).
A boosted gate-drive voltage is generated by an internal charge pump to enhance the performance of the
RGB switches. 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. The RGB switches function with
reduced performance when the charge pump is disabled (V+ > 5V). The MAX4887’s global input (EN)
places all inputs/outputs in a high-impedance state,
providing rejection of all signals.
The R_, G_, and B_ analog switches are identical, and
any of the three switches can be used to route red,
green, or blue video signals. All RGB inputs/outputs are
ESD protected to ±8kV Human Body Model (HBM).
Analog Signal Levels
Analog signal inputs over the full voltage range (0 to
V+) are passed through the switch with minimal change
in on-resistance (QP = low). When QP = high, the
switches can operate within 1V of V+. The switches are
bidirectional; therefore, R_, G_, and B_ can be either
inputs or outputs.

Charge Pump
A low-noise charge pump with internal capacitors provides a doubled voltage for driving the RGB analog
switches when operating the MAX4887 at low voltages
(V+ < 5V). The charge pump adds less than 163µV
P-P
of noise to the switches. When operating with V+ = 5V,
the charge pump can be disabled to further reduce
noise; however, the analog switch’s performance is
slightly degraded resulting in higher R
ON
and insertion
loss. Drive QP high to disable the charge pump. Drive
QP low for normal operation.
When operating the MAX4887 at 3.3V, connect QP
to GND.
Logic Inputs (EN, SEL)
The MAX4887 has two logic inputs that control the
switch configuration and on/off function. Use SEL to
switch (RGB)0to (RGB)1 or (RGB)2. Use EN to connect
the switch inputs to the outputs. Drive EN low to enable
the RGB switches inputs/outputs. Drive EN high to
place all inputs/outputs in a high-impedance state.

Applications Information
Power-Supply Bypassing and Sequencing
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the device.
Always sequence V+ on first, followed by R_, G_, or B_
and the logic inputs. Bypass V+ to ground with a 0.1µF
or larger ceramic capacitor as close to the device as
possible.
Layout
High-speed switches such as the MAX4887 require
proper PC board layout for optimum performance.
Ensure that impedance-controlled PC board traces for
high-speed signals are matched in length and as short
as possible. Connect the exposed paddle to a solid
ground plane.
ESD Protection
As with all Maxim devices, ESD-protection structures
are incorporated to protect against electrostatic discharges encountered during handling and assembly on
all pins. Additionally, the MAX4887 is protected to ±8kV
Human Body Model (HBM) on all switches.
Human Body Model
Several ESD testing standards exist for measuring the
robustness of ESD structures. The ESD protection of
the MAX4887 is characterized with the Human Body
Model. Figure 6 shows the model used to simulate an
ESD event resulting from contact with the human body.
The model consists of a 100pF storage capacitor that is
charged to a high voltage, then discharged through a
1.5kΩ resistor. Figure 7 shows the current waveform
when the storage capacitor is discharged into a low
impedance.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Please contact Maxim for a reliability report documenting test setup, methodology, and results.
Additional Applications Information
Figure 8 illustrates the MAX4887 being used in a laptop
in a 2:1 configuration (one of two sources connected to
a load). The switch assumes the dedicated DVD player
chip outputs R, G, B video, and the MAX4887 switches
between normal VGA graphics and the dedicated DVD
device.

NOTES:
1. DIMENSIONING & TOLERANCING CONFORM TO ASME Y14.5M-1994.
2. ALL DIMENSIONS ARE IN MILLIMETERS. ANGLES ARE IN DEGREES.
3. N IS THE TOTAL NUMBER OF TERMINALS.
4. THE TERMINAL #1 IDENTIFIER AND TERMINAL NUMBERING CONVENTION SHALL CONFORM TO
JESD 95-1 SPP-012. DETAILS OF TERMINAL #1 IDENTIFIER ARE OPTIONAL, BUT MUST BE LOCATED
WITHIN THE ZONE INDICATED. THE TERMINAL #1 IDENTIFIER MAY BE EITHER A MOLD OR
MARKED FEATURE.
5. DIMENSION b APPLIES TO METALLIZED TERMINAL AND IS MEASURED BETWEEN 0.20 mm AND 0.25 mm
FROM TERMINAL TIP.
6. ND AND NE REFER TO THE NUMBER OF TERMINALS ON EACH D AND E SIDE RESPECTIVELY.
7. DEPOPULATION IS POSSIBLE IN A SYMMETRICAL FASHION.
8. COPLANARITY APPLIES TO THE EXPOSED HEAT SINK SLUG AS WELL AS THE TERMINALS.
9. DRAWING CONFORMS TO JEDEC MO220 REVISION C.
10. MARKING IS FOR PACKAGE ORIENTATION REFERENCE ONLY.
