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

28-Port LED Display Driver and I/O Expander

General Description

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.

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 I

C-compatible 2-wire serial

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

addresses from only 2 select pins.

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.
