ICM7211AIJL

Display Drivers Overview

The ICM7211AIJL is a four-digit, seven-segment CMOS LCD display decoder-driver manufactured by Analog Devices Inc./Maxim Integrated. 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 frequency generation. Designed for through-hole installation, it utilizes a 40-pin CERDIP package and functions reliably across an operating temperature range of -20°C to +85°C.

Display Drivers Feature Summary

• Integrates complete decoding logic with data and digit address latches controlled by chip select inputs for direct processor interfacing.
• Includes an onboard RC oscillator and divider chain to generate the required backplane frequency without external components.
• Provides backplane input/output capabilities to enable simple synchronization between master and slave devices.

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Microprocessor-based instrumentation readouts
• Industrial control panel interfaces

Display Drivers Procurement Notes

Verify component authenticity and RoHS compliance status carefully, as historical records indicate potential lead-containing variants. Confirm package integrity upon receipt, specifically checking for ceramic DIP housing defects. Ensure design compatibility with existing power supply rails and clock frequencies before integration into final assemblies.

Display Drivers Selection Notes

Select this component when a dedicated solution for driving four-digit seven-segment LCDs is required without multiplexing complexity. It is suitable for designs needing integrated timing generation and latch functionality to simplify microprocessor interface circuitry. Consider thermal dissipation limits and package availability constraints during the selection process.
