MAX14434–MAX14436 Evaluation Kit
General Description
The MAX14434–MAX14436 evaluation kit (EV kit)
provides a proven design to evaluate the MAX14434–
MAX14436 four-channel unidirectional digital isolators.
Three types of evaluation boards are available to support
different channel direction configurations of the
MAX14434–MAX14436 family. All evaluation boards
support the wide-body 16-pin SOIC package type. See
Table 1 for EV kit options.
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 MAX14434FWEVKIT# comes populated with
MAX14434FAWE+, but can also be used to evaluate the following digital isolators: MAX14434BAWE+,
MAX14434CAWE+,
MAX14434EAWE+.
The
MAX14435FWEVKIT# comes populated with the
MAX14435FAWE+ but can also be used to evaluate the
following isolators: MAX14435CAWE+, MAX14435BAWE+,
MAX14435EAWE+, MAX14435RAWE+, MAX14435SAWE+,
MAX14435UAWE+, and MAX14435VAWE+.

MAX14434–MAX14436 Evaluation Kit
Quick Start
• 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.
Required Equipment
●● MAX14434FW, MAX14435FW, or MAX14436FW
●● Two DC power supplies with output range of 1.71V
to 5.5V
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.
●● Signal/function generator
●● Oscilloscope
Procedure
The MAX14434FW, MAX14435FW, and MAX14436FW
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.
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.
4) Connect the signal/function generator to an input SMA
connector or test point of side A and observe the isolated signal on the corresponding side B output, using an
oscilloscope.

MAX14434–MAX14436 Evaluation Kit
Detailed Description of Hardware
Evaluates: MAX14434–MAX14436
Termination
The EV kits are powered from two power supplies as
described below.
External Power Supplies
Power to the MAX14434FW, MAX14435FW, and
MAX14436FW EV kits is derived from two external sources
which can both be between +1.71V and +5.5V. Connect
one source between the VDDA and GNDA test points, and
the other source between the VDDB and GNDB test points.
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 MAX14434MAX14436 level-shift the data, transmitting them across
the isolation barrier.
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.
Decoupling Capacitors
Each power supply is decoupled with a 10µF ceramic
capacitor in parallel with a 0.1µF ceramic capacitor, which
are placed close to the U1 VDDA and VDDB pin.
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.
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 MAX14434-MAX14436 supply current.
Jumper ENA is provided to enable or disable the side A of
the isolator channels. To enable the devices with activehigh enable pin on the side A (MAX1443_B/C/E/F), connect the ENA shunt to VDDA. To enable the devices with
active-low enable pin on the side A (MAX14435R/S/U/V),
connect the ENA shunt to GNDA. The side A outputs are
high-impedance when disabled.
Jumper ENB is provided to enable or disable the side B of
the isolator channels. Connect the ENB shunt to VDDB to
enable the side B channels, or connect to GNDB to disable
the side B channels. The side B outputs are high-impedance
when disabled. See Table 2 for all shunt positions.
