ICM7218DIQI LED Driver 7-Segment 8-Digit Display Controller

Part Overview

The ICM7218DIQI is a LED driver integrated circuit designed for controlling 7-segment, 8-digit display applications. Manufactured by Analog Devices Inc./Maxim Integrated, this component operates as a parallel interface driver with a supply voltage range of 2V to 6V and minimal current consumption of 250 µA. The device is packaged in a 28-PLCC (11.51x11.51mm) surface mount configuration.

The ICM7218DIQI carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. Active substitute components maintain identical electrical and mechanical specifications while offering current manufacturing support and updated compliance certifications.

Substitute Part Grouping Explanation

Substitution of the ICM7218DIQI is determined by strict equivalence across the following critical parameters:

• Display Type: LED
• Configuration: 7 Segment
• Digits or Characters: 8 Digits
• Interface: Parallel
• Voltage - Supply: 2V ~ 6V
• Current - Supply: 250 µA
• Operating Temperature: -20°C ~ 85°C
• Package / Case: 28-LCC (J-Lead)
• Supplier Device Package: 28-PLCC (11.51x11.51)

The ICM7218DIQI+ qualifies as a direct substitute, maintaining identical electrical performance and mechanical compatibility while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ICM7218DIQI+ is the appropriate selection for applications requiring an active, supported component. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs.

The primary distinction between the two parts is product lifecycle status and regulatory compliance. The ICM7218DIQI+ carries active product status with ROHS3 compliance certification, whereas the ICM7218DIQI is obsolete and RoHS non-compliant. For new designs and production environments subject to regulatory requirements, the ICM7218DIQI+ is the specified choice.

Both components are manufactured by Analog Devices Inc./Maxim Integrated and share the same base product number (ICM7218), confirming design equivalence.

Frequently Asked Questions (FAQ)
