MAX6954APL+

Display Drivers Overview

The MAX6954APL+ is an LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It supports 14-segment or 16-segment displays with a 3-line serial interface. The device operates on a supply voltage range of 2.7V to 5.5V and features a maximum supply current of 6.7 mA. It provides high-level output currents up to 30 mA and low-level sink currents up to 275 mA. The component is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Display Drivers Feature Summary

• Supports direct driving of 14-segment or 16-segment alphanumeric displays
• Utilizes a 3-wire serial interface for simplified system connectivity
• Integrates internal oscillator and current regulation circuitry

Display Drivers Applications

• Alphanumeric display modules requiring 14-segment or 16-segment characters
• Industrial control panels with segmented LED readouts
• Consumer appliances featuring multi-character numeric displays

Display Drivers Procurement Notes

Verify the specific suffix 'PL' corresponds to the 28-pin SSOP package variant when sourcing. Confirm the operating temperature grade matches the application requirements, as industrial variants typically cover -40°C to +85°C. Ensure the design accounts for the 3-wire serial interface timing specifications provided in the official datasheet to guarantee reliable communication with the host microcontroller.

Display Drivers Selection Notes

Select this component for designs requiring dedicated drivers for complex alphanumeric segments rather than standard 7-segment displays. The integrated current regulation simplifies resistor selection compared to multiplexed solutions. Consider the pin count and package size relative to available PCB space, as the 28-pin SSOP requires specific footprint dimensions distinct from smaller 16-pin alternatives.

Display Drivers Part Context

This part belongs to the MAX695x family of LED display drivers designed for alphanumeric applications. Unlike simpler 7-segment drivers, this series addresses the complexity of 14-segment and 16-segment layouts used for letters and symbols. The family shares common interface protocols but varies in segment capacity and package options to suit different density requirements.

Display Drivers Replacement Considerations

Cross-reference with other MAX695x family members such as the MAX6955 or MAX6956 if segment count or package type differs. Verify that any substitute maintains compatibility with the 3-wire serial protocol and physical pinout to ensure board-level interchangeability without schematic modifications.
