MAX6956APL

Drivers, Receivers, Transceivers Overview

The MAX6956APL is a compact, serial-interfaced LED display driver and I/O expander manufactured by Analog Devices Inc./Maxim Integrated. It provides microprocessors with up to 28 individually configurable ports. Each port can be set as a logic input, logic output, or common-anode LED constant-current segment driver. The device operates on a supply voltage ranging from 2.5V to 5.5V and supports an I2C-compatible serial interface with a data rate of 400kbps. It features 16-step programmable current control for each LED, allowing current settings from 1.5mA to 24mA. The component is designed for operation within a temperature range of -40°C to +125°C and includes a shutdown mode with a maximum current consumption of 11µA.
