ICM7211AMIQH+D

Display Drivers Overview

The ICM7211AMIQH+D is a four-digit, non-multiplexed LCD display decoder-driver manufactured by Analog Devices Inc. (formerly Maxim Integrated). It integrates a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs within a single CMOS device. The component operates with a maximum clock frequency of 16 kHz and utilizes a PLCC-44 package. Designed for direct high-speed processor interface, it provides data input latches and digit address latches controlled by chip select inputs.

Display Drivers Feature Summary

• Integrates a complete onboard RC oscillator to generate the required backplane frequency without external timing components.
• Features a backplane input/output capability that allows simple synchronization of slave devices to a master unit.
• Provides dedicated data and digit address latches controlled by chip select inputs to facilitate a direct high-speed processor interface.

Display Drivers Applications

• Four-digit non-multiplexed seven-segment LCD display systems
• Direct microprocessor interfacing applications requiring high-speed data transfer
• Synchronized multi-device LCD control architectures

Display Drivers Procurement Notes

Verify the specific suffix 'QH+D' against official Analog Devices documentation to confirm package type and lead-free compliance status. Ensure the source document explicitly lists this exact part number variant, as distributor listings may group similar ICM7211 models. Confirm RoHS compliance details directly from the manufacturer's datasheet rather than relying on third-party summaries.

Display Drivers Selection Notes

Select this component when a non-multiplexed four-digit LCD solution is required with integrated timing generation. The PLCC-44 package suits surface-mount designs needing 28 segment outputs. Consider the onboard RC oscillator if minimizing external passive components is a priority. Verify that the parallel BCD input interface matches the host processor's output capabilities.

Display Drivers Part Context

This device belongs to the ICM7211 series of LCD drivers, designed for straightforward decoding and driving of seven-segment displays. Unlike multiplexed alternatives, this model supports direct digit addressing, simplifying software logic. The series is characterized by CMOS technology, offering low power consumption suitable for battery-operated or portable instrumentation applications.

Display Drivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other ICM7211 variants such as ICM7211AMIQH or ICM7211AI/D only if pinout and electrical specifications match exactly. No alternative part numbers are verified for direct replacement based on current data.
