MAX7232BFIQH+D

Display Drivers Overview

The MAX7232BFIQH+D is a triplexed liquid crystal display (LCD) driver from the MAX7231/32/33/34 family, manufactured by Analog Devices Inc./Maxim Integrated. It is designed to drive up to ten digits of a multiplexed LCD panel with seven segments each. The device integrates charge pump circuitry for internal voltage generation, eliminating the need for external high-voltage supplies. Housed in a 44-pin Plastic Leaded Crystal Carrier (PLCC) package, it supports direct interfacing with microcontrollers or logic circuits for display control applications.

Display Drivers Feature Summary

• Integrates on-chip charge pump for internal voltage generation without external high-voltage components
• Supports driving up to ten digits of a multiplexed LCD panel with seven segments per digit
• Designed as part of a complete line of triplexed LCD drivers for simplified system design

Display Drivers Applications

• Triplexed liquid crystal display systems
• Multiplexed LCD panel driving
• Seven-segment digital display interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'D' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the component matches the 44-PLCC physical footprint. Check for RoHS compliance status if required by assembly specifications. Validate the part number against official distributor catalogs to avoid counterfeit units.

Display Drivers Selection Notes

Select this component for applications requiring a dedicated driver for triplexed LCDs with up to ten digits. Consider the 44-PLCC package constraints for PCB layout. Evaluate power supply requirements based on the integrated charge pump capabilities. Compare against other members of the MAX723x family if different segment counts or pin configurations are needed.

Display Drivers Part Context

This component belongs to the MAX7231/32/33/34 family of integrated circuits, which constitute a complete line of triplexed LCD drivers. These devices are engineered to simplify the interface between digital logic and multiplexed displays. The MAX7232 variant specifically addresses designs requiring support for ten-digit, seven-segment displays within a compact form factor.

Display Drivers Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers within the MAX723x family. Verify pin compatibility and electrical characteristics before substituting with other LCD drivers. Generic replacements may not match the specific triplexing requirements or package dimensions.
