2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or  
28-Port LED Display Driver and I/O Expander  
General Description  
Features  
o 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.  
o 2.5V to 5.5V Operation  
o -40°C to +125°C Temperature Range  
o 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.  
o 11µA (max) Shutdown Current  
o 16-Step Individually Programmable Current  
Control for Each LED  
o Logic Transition Detection for Seven I/O Ports
