ICM7211AI/D

Display Drivers Overview

The ICM7211AI/D is a liquid crystal display driver manufactured by Analog Devices Inc./Maxim Integrated. It is designed for four-digit, seven-segment displays and utilizes CMOS technology. The device operates within a power supply voltage range of 3 V to 6 V and supports a maximum clock frequency of 16 kHz. It features a low maximum power supply current of 10 uA and a power dissipation rating of 500 mW. The component functions in an operating temperature range from -20°C to +85°C and is available in a PLCC-44 surface-mount package.

Display Drivers Feature Summary

• Integrates decoding and driving capabilities for four-digit LCD segments
• Operates with low power consumption suitable for battery applications
• Supports parallel data input modes for direct interfacing

Display Drivers Applications

• Four-digit LCD numeric displays
• Seven-segment indicator systems
• Low-power consumer electronics instrumentation

Display Drivers Procurement Notes

Verify the specific suffix 'D' indicates the die configuration rather than a standard packaged form factor when sourcing. Confirm RoHS compliance status as documentation may vary between legacy Maxim and current Analog Devices records. Ensure the design accommodates the PLCC-44 footprint if using packaged equivalents or verify die-level handling requirements for the specific part variant.

Display Drivers Selection Notes

Select this component for designs requiring integrated decoding for simple four-digit LCD interfaces. Consider the 3 V to 6 V supply range compatibility with standard logic levels. Evaluate the thermal performance given the 500 mW dissipation limit. Verify that the parallel interface meets system timing constraints at the 16 kHz maximum clock rate.

Display Drivers Part Context

This part belongs to the ICM7211A series of LCD drivers originally developed by Maxim Integrated, now under Analog Devices. The series provides dedicated solutions for multiplexed or static LCD displays. The 'AI' designation typically refers to the industrial temperature grade and specific process variation within the family.
