Digital Control Inputs
The MAX4890E/MAX4892E provide a single digital con-
trol SEL. SEL controls the switches as well as the LED
switches as shown in Table 1.
Analog Signal Levels
The on-resistance of the MAX4890E/MAX4892E is very
low and stable as the analog input signals are swept
from ground to V+ (see the Typical Operating
Characteristics). The switches are bidirectional, allow-
ing A_ and _B_ to be configured as either inputs or out-
puts.
ESD Protection
The MAX4890E/MAX4892E are characterized using the
Human Body Model for ±15kV of ESD protection. Figure 5
shows the Human Body Model. This model consists of a
100pF capacitor charged to the ESD voltage of interest
which is then discharged into the test device through a
1.5k
resistor. All signal and control pins are ESD pro-
tected to ±15kV HBM (Human Body Model).
Applications Information
Typical Operating Circuit
The Typical Operating Circuit shows the MAX4890E/
MAX4892E in a 1000 Base-T docking station application.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum ratings.
Stresses beyond the listed ratings may cause perma-
nent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not
current limited.
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Keep design-con-
trolled-impedance pc board traces as short as possible.
Ensure that bypass capacitors are as close as possible
to the device. Use large ground planes where possible.
