ICM7224IQH

Display Drivers Overview

The ICM7224IQH is a 4 1/2 digit LCD driver and high-speed counter-decoder manufactured by Analog Devices Inc./Maxim Integrated. It features a 30-segment output capability and operates with a maximum clock frequency of 19 kHz. The device supports a supply voltage range from 3 V to 3.6 V, with a maximum power dissipation of 1 W. It is housed in a 44-PLCC package (16.59x16.59 mm) designed for surface mount installation. The component functions within an operating temperature range of -20°C to +85°C.

Display Drivers Feature Summary

• Integrates a high-speed counter-decoder with a 4 1/2 digit LCD display driver
• Provides symmetrical or asymmetrical positive and negative voltage outputs up to 10.5V
• Features low power consumption with a shutdown current of 10µA

Display Drivers Applications

• Digital panel meters requiring 4 1/2 digit resolution
• Portable battery-powered instrumentation
• Industrial control systems with LCD interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'IQH' against official datasheets to confirm the 44-PLCC package variant. Confirm availability status as restricted supply may apply. Ensure the operating temperature range matches system requirements. Validate RoHS compliance documentation for the specific manufacturing batch.

Display Drivers Selection Notes

Select this component when a combined counter-decoder and LCD driver is required for 4 1/2 digit displays. Consider the 44-PLCC surface mount package for PCB layout constraints. Evaluate the 10µA shutdown current for battery life optimization in portable applications. Verify compatibility with the required segment count and voltage levels.

Display Drivers Part Context

This part belongs to the ICM7224 series of LCD drivers. It is distinct from the ICM7224IPL+ which uses a PDIP-40 through-hole package. The IQH suffix denotes the plastic leaded chip carrier package variant. It serves as a specialized solution for integrating counting and display driving functions in a single integrated circuit.

Display Drivers Replacement Considerations

The ICM7224IPL+ is a functional equivalent but utilizes a PDIP-40 through-hole package instead of the 44-PLCC surface mount format. Verify pinout compatibility and mechanical footprint differences before substitution.
