MAX14430–MAX14432 Evaluation Kit
Evaluates: MAX14430–MAX14432
The MAX14432FSEVKIT# comes populated with the
MAX14432FASE+, but can also be used to evaluate the
following digital isolators:
General Description
The MAX14430-MAX14432 evaluation kit (EV kit) provides
a proven design to evaluate the MAX14430-MAX14432
four-channel unidirectional digital isolators. Three types of
evaluation boards are available to support different chan-
nel direction configurations of the MAX14430-MAX14432
family. All evaluation boards support the narrow-body
16-pin SOIC package type. See Table 1 for EV kit options.
MAX14432BASE+
MAX14432CASE+
MAX14432EASE+
The MAX14430EAEE+ and MAX14431CAEE+ have
the same functionality and electrical performance as
the MAX14430EASE+ and MAX14431CASE+, but in
a 16-QSOP package. The MAX14432FSEVKIT# can
be used to evaluate the electrical performance of the
MAX14430EAEE+ and MAX14431CAEE+ with the
MAX14430EASE+ or MAX14431CASE+ installed as U1.
The EV kit should be powered from two independent
isolated power supplies with nominal output voltage in
range from 1.71V to 5.5V. For evaluating the electrical
parameters of the device without any isolation between
the two sides, a single power supply can also be used.
The MAX14430FSEVKIT# comes populated with a
MAX14430FASE+, but can also be used to evaluate the
following digital isolators:

2) Connect one DC power supply between the EV kit’s
TP_VDDA and TP_GNDA test points; connect the
other DC power supply between TP_VDDB and TP_
GNDB test points.
Quick Start
Required Equipment
● MAX14430FS, MAX14431FS, or MAX14432FS EV kit
● Two DC power supplies with output range of 1.71V
3) Set both DC power supply outputs between 1.71V
and 5.5V, and then enable the power supply outputs.
Note: It is also possible to power the EV kits from a
single power supply to test electrical parameters but
this invalidates the digital isolation of the IC.
to 5.5V
● Signal/function generator
● Oscilloscope
Procedure
4) Connect the signal/function generator to the SMA
connector or test point of side A and observe the
isolated signal on the corresponding side B output,
using an oscilloscope.
The MAX14430FS, MAX14431FS, and MAX14432FS
EV kits are fully assembled and ready for evaluation. For
manual verification follow the steps below to verify board
functionality:
1) Verify jumper settings. See Table 2 for all shunt positions.
• J1 and J2 are closed.
• Jumper ENA is either in 1-2 position if U1 ENA (pin
7) has active-high polarity, or in 2-3 position if U1
ENA (pin 7) has active-low polarity.
• Jumper ENB is in 1-2 position.

Termination
Detailed Description of Hardware
Each input and output has an unpopulated 0603 SMT
resistor (RA1-RA4, RB1-RB4) and an unpopulated 0603
SMT capacitor (CA1-CA4, CB1-CB4) to GND_ to allow
termination based on customer requirements.
The EV kits are powered from two power supplies as
described below.
External Power Supplies
Power to the MAX14430FS, MAX14431FS, and
MAX14432FS EV kits are derived from two external sources
which can both be between +1.71V and +5.5V. Connect
Shunt Positions
Jumpers J1 and J2 are installed between the external
power supplies and U1 power supply pins to allow supply
current measurement. Uninstall the J1 and J2 shunts and
connect current meters on both side A and side B to measure
the MAX14430–MAX14432 supply current.

the other source between the V
DDB
and GNDA test points, and
and GNDB test points.
DDA
Each supply can be set independently and can be present
over the entire range from 1.71V to 5.5V, regardless of the
level or presence of the other supply. The MAX14430–
MAX14432 level-shift the data, transmitting them across
the isolation barrier.
Jumper ENA is provided to enable or disable the side
A of the isolator channels. To enable the devices with
active-high enable pin on the side A (MAX1443_B/C/E/F),
connect the ENA shunt to V
. To enable the devices
Four SMA connectors on each side of the board allow
easy connections to signal generator(s) and oscilloscope.
A typical test setup is shown in Figure 2.

with active-low enable pin on the side A (MAX14431R/S/
U/V), connect the ENA shunt to GNDA. The side A outputs
are high-impedance when disabled.
Decoupling Capacitors
Each power supply is decoupled with a 10µF ceramic
capacitor in parallel with a 0.1µF ceramic capacitor, which
Jumper ENB is provided to enable or disable the side B of
the isolator channels. Connect the ENB shunt to V

when disabled. See Table 2 for all shunt positions.
