• Operating Supply Voltage: 2.5 V to 5.5 V

The I
jumper settings of JU0, JU1, and JU2. The I2C
Addresses drop-down list automatically detects the
MAX7311’s I
starts. The default I
shipped, is 0x40.
If the jumper settings of JU0, JU1, and JU2 change,
press the Reconnect button to automatically detect the
new I
The MAX7311 has 16 I/Os, configurable as push-pull
outputs or inputs. The MAX7311 EV kit board provides
a proven layout for evaluating the MAX7311. The EV kit
comes with a MAX7311ATG+ installed.
The combinations of shunt position of jumpers JU0,
JU1, and JU2 determine the I
MAX7311 device. Refer to the MAX7311 IC data sheet
for appropriate settings.

MAX7311 Evaluation Kit
There are eight red LEDs and eight green LEDs on the EV
kit to demonstrate the push-pull capability of the I/Os.
When an I/O is configured as an output and the logic level
is high, the corresponding red LED will be on and the
green LED will be off. If the logic level is low, the corre-
sponding green LED will be on and the red LED will be off.
Two pullup resistors and two pushbuttons are connected
to I/O8 and I/O9 of the MAX7311. Press pushbutton S2 to
drive I/O8 low and press pushbutton S1 to drive I/O9 low.
By default, the MAX7311 EV kit is powered by USB. To
use the user-supplied power supply, place a shunt on
pins 2-3 of JU5, cut the trace between pins 1-2 of JU5,
and connect a 2.5V to 3.3V power supply to the VIN pad.
To use the MAX7311 EV kit with a user-supplied I
interface, install shunts on pins 2-3 of JU3 and JU4.
Connect SDA, SCL, and GND lines from the user-
supplied I
on the MAX7311 EV kit. Place a shunt on pins 2-3 of
JU5, cut the trace between pins 1-2 of JU5, and con-
nect a 2V to 5.5V power supply to the VIN pad.
