ICM7211AMIQH+TD

Display Drivers Overview

The ICM7211AMIQH+TD is a four-digit, non-multiplexed LCD display decoder-driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 3 V to 6 V and supports a maximum clock frequency of 16 kHz. The device features 28 segment outputs and is housed in a PLCC-44 surface-mount package. It functions within an operating temperature range of -20°C to +85°C with a maximum power dissipation of 500 mW.

Display Drivers Feature Summary

• Integrates a complete onboard RC oscillator to generate backplane frequency without external components.
• Provides direct high-speed processor interface through data and digit address latches controlled by chip select inputs.
• Includes backplane input/output capability for simple synchronization of slave devices to a master unit.

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Microprocessor-based instrumentation requiring direct drive interfaces
• Digital readout units in industrial control panels

Display Drivers Procurement Notes

Verify the specific suffix +TD indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated in official documentation. Check humidity sensitivity classification prior to storage or assembly. Ensure the PLCC-44 footprint matches the target PCB design constraints.

Display Drivers Selection Notes

Select this component for applications requiring integrated decoding and driving of four-digit LCDs. The onboard oscillator simplifies circuit design by reducing external component count. Verify that the parallel interface requirements align with the host microcontroller's capabilities and voltage levels.

Display Drivers Part Context

This part belongs to the ICM7211A series of CMOS LCD display drivers. It is designed to replace older discrete logic solutions by integrating decoding, latching, and driving functions into a single IC. The Maxim Integrated branding reflects its lineage from the original Intersil product line acquired by Analog Devices.

Display Drivers Replacement Considerations

Direct substitutes include other variants within the ICM7211A family, such as ICM7211AIQH+TD, which may differ only in packaging or temperature grade. Cross-reference pinouts and electrical specifications before substitution.
