MAX6956AAX+

The MAX6956AAX+ is a 2 wire interfaced, 2.5V to 5.5V, 28 port LED display driver and I/O expander in 36 pin SSOP package. The compact, serial interfaced LED display driver/I/O expander provides microprocessors with up to 28 ports. Each port is individually user configurable to 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 sinking 10mA and sourcing 4.5mA or a Schmitt logic input with optional internal pull-up. Seven ports feature configurable transition detection logic which generates an interrupt upon change of port logic level.

• 16 step individually programmable current control for each LED
• Operating temperature range from -40°C to 125°C
• I2C compatible serial interface is 400Kbps
• Maximum shutdown current is 11μA
• Uses four level logic to allow 16 I2C addresses from 2 select pins
