ICM7211IPL+

Display Drivers Overview

The ICM7211IPL+ is a four-digit, non-multiplexed CMOS 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 includes an onboard RC oscillator for backplane generation. Designed for through-hole mounting, it utilizes a PDIP-40 package and functions reliably across an operating temperature range of -20°C to +85°C.

Display Drivers Feature Summary

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

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Microprocessor-based instrumentation requiring direct drive interfaces
• Industrial control panels with segmented LCD readouts

Display Drivers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance details and moisture sensitivity levels prior to assembly. Ensure packaging specifications match design requirements, as tube quantities may vary. Cross-reference datasheet revisions to confirm pinout compatibility with existing PCB layouts before finalizing procurement orders.

Display Drivers Selection Notes

Select this component when designing systems requiring dedicated four-digit LCD decoding without multiplexing complexity. The integrated oscillator simplifies circuit design by eliminating external timing components. Consider the PDIP-40 package constraints for board space and thermal management. Verify that the 3 V to 6 V supply range aligns with the target system power architecture and that the 16 kHz clock limit meets display refresh requirements.

Display Drivers Part Context

This part belongs to the ICM7211A series of LCD drivers from Analog Devices/Maxim Integrated. It serves as a specialized decoder-driver for segmented displays, distinct from LED driver variants like the ICM7212. The ICM7211IPL+ specifically denotes the industrial temperature grade variant housed in a 40-pin PDIP package, offering robust performance for commercial and industrial applications.

Display Drivers Replacement Considerations

The ICM7211AMlPLZ is a lead-free equivalent within the same family. For surface-mount needs, the PLCC-44 variants such as ICM7211AIQH+D offer functional parity with different packaging. Verify electrical parameters and pin compatibility before substituting.
