Applications Information
Power-Supply Bypassing and Sequencing
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings 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 0.1F
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 dis-
charges 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
1.5k
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 document-
ing 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.
