ICM7218BIQI+T

Display Drivers Overview

The ICM7218BIQI+T is an 8-digit multiplexed LED decoder driver manufactured by Analog Devices Inc./Maxim Integrated. It features a 28-pin PLCC surface-mount package and operates on a parallel interface. The device supports a supply voltage range of 2V to 6V, with a maximum operating temperature of +85°C and a minimum of -40°C. It consumes a maximum supply current of 950 µA and dissipates up to 1W of power. The component is designed for driving common-cathode or common-anode 7-segment LED displays.

Display Drivers Feature Summary

• Integrated 8-digit multiplexed decoding and driving capability for direct LED segment control
• Supports both common-cathode and common-anode display configurations via internal logic
• Parallel data interface allows straightforward connection to microcontroller GPIOs
• Built-in oscillation circuitry eliminates the need for external timing components

Display Drivers Applications

• Digital panel meters requiring multi-digit numeric readouts
• Industrial control systems with local status display interfaces
• Consumer appliances featuring segmented LED information screens
• Test equipment displaying measurement values on front panels

Display Drivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly processes. Confirm RoHS compliance status through official manufacturer documentation, as legacy variants may differ. Ensure the 28-PLCC footprint matches the target PCB layout. Validate that the -40°C to +85°C industrial temperature range meets environmental requirements. Cross-reference the exact part number with Analog Devices to confirm current production status and availability constraints.

Display Drivers Selection Notes

Select this component when an 8-digit 7-segment display requires dedicated decoding without MCU overhead. The parallel interface suits designs where GPIO count is sufficient. Consider the 2V–6V supply range compatibility with system rails. Evaluate the PLCC package against available surface-mount assembly capabilities. Compare power dissipation limits against thermal management strategies in enclosed enclosures.

Display Drivers Part Context

This part belongs to the ICM7218 family of LED display drivers from Maxim Integrated, now part of Analog Devices. The 'B' variant typically denotes specific pinout or functional characteristics within the series. The 'IQI' suffix identifies the 28-lead Plastic Leaded Chip Carrier (PLCC) package type. The '+T' suffix generally signifies lead-free composition and tape-and-reel shipping format.

Display Drivers Replacement Considerations

Direct substitutes include ICM7218AIQI+T and ICM7218CIQI+T, which share similar functionality but may differ in electrical specifications or package tolerances. Verify pin compatibility and logic levels before substitution.
