2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or

28-Port LED Display Driver and I/O Expander

MAX956

General Description

Features

ꢀ 400kbps I²C-Compatible Serial Interface

The MAX6956 compact, serial-interfaced LED display

driver/I/O expander provide microprocessors with up to

28 ports. Each port is individually user configurable to

either a logic input, logic output, or common-anode

(CA) LED constant-current segment driver. Each port

configured as an LED segment driver behaves as a

digitally controlled constant-current sink, with 16 equal

current steps from 1.5mA to 24mA. The LED drivers are

suitable for both discrete LEDs and CA numeric and

alphanumeric LED digits.

ꢀ 2.5V to 5.5V Operation

ꢀ -40°C to +125°C Temperature Range

ꢀ 20 or 28 I/O Ports, Each Configurable as

Constant-Current LED Driver

Push-Pull Logic Output

Schmitt Logic Input

Schmitt Logic Input with Internal Pullup

Each port configured as a general-purpose I/O (GPIO)

can be either a push-pull logic output capable of sink-

ing 10mA and sourcing 4.5mA, or a Schmitt logic input

with optional internal pullup. Seven ports feature config-

urable transition detection logic, which generates an

interrupt upon change of port logic level. The MAX6956

is controlled through an I²C-compatible 2-wire serial

interface, and uses four-level logic to allow 16 I²C

addresses from only 2 select pins.

ꢀ 11µA (max) Shutdown Current

ꢀ 16-Step Individually Programmable Current

Control for Each LED

ꢀ Logic Transition Detection for Seven I/O Ports

PIN-PACKAGE

28 DIP

The MAX6956AAX and MAX6956ATL have 28 ports

and are available in 36-pin SSOP and 40-pin thin QFN

packages, respectively. The MAX6956AAI and

MAX6956ANI have 20 ports and are available in 28-pin

SSOP and 28-pin DIP packages, respectively.

For an SPI-interfaced version, refer to the MAX6957

data sheet. For a lower cost pin-compatible port

expander without the constant-current LED drive capa-

bility, refer to the MAX7300 data sheet.
