MAX7219ENG LED Driver IC - Equivalent & Substitute Parts

Part Overview

The MAX7219ENG is a serial input/output common-cathode display driver manufactured by Analog Devices Inc./Maxim Integrated. It controls up to 8 digits of 7-segment LED displays plus decimal points through a 4-wire serial interface. The device operates from 4V to 5.5V supply voltage with a maximum supply current of 330 mA and supports operating temperatures from -40°C to 85°C in a 24-pin DIP package.

The MAX7219ENG is classified as obsolete. Locating equivalent or substitute parts becomes necessary when original stock is depleted or when design updates require components with current manufacturing status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX7219ENG is determined by strict equivalence across the following parameters:

• Display Type: LED
• Configuration: 7 Segment + DP
• Digits or Characters: 8 Digits
• Interface: 4-Wire Serial
• Voltage - Supply: 4V ~ 5.5V
• Current - Supply: 330 mA
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Through Hole
• Package / Case: 24-DIP (0.300", 7.62mm)

The MAX7219ENG+ meets all these electrical and mechanical parameters identically. The primary distinction between the main part and its substitute is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The MAX7219ENG+ is a direct functional equivalent to the MAX7219ENG. Both parts share identical electrical specifications, pin configuration, and mechanical package dimensions. The MAX7219ENG+ is the preferred selection for new designs and component replenishment due to its active product status and ROHS3 compliance certification. The MAX7219ENG remains suitable for legacy system maintenance where existing inventory is available and RoHS compliance is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can MAX7219ENG+ be used as a direct replacement for MAX7219ENG in existing designs?

A: Yes. The MAX7219ENG+ is electrically and mechanically identical to the MAX7219ENG. Pin-for-pin compatibility is complete. No circuit modifications are required.

Q: What is the difference between MAX7219ENG and MAX7219ENG+?

A: The primary differences are product status and compliance. The MAX7219ENG is obsolete and RoHS non-compliant. The MAX7219ENG+ is active production and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any package differences between these parts?

A: Both parts use the 24-DIP (0.300", 7.62mm) package with 24-PDIP supplier device package designation. The MAX7219ENG+ is supplied in tube packaging, while the MAX7219ENG packaging type is not specified.

Q: What are the key parameters that define substitution for the MAX7219ENG?

A: Substitution is determined by matching display type (LED), configuration (7 Segment + DP), digit count (8), interface type (4-Wire Serial), supply voltage range (4V ~ 5.5V), supply current (330 mA), operating temperature range (-40°C ~ 85°C), mounting type (Through Hole), and package specification (24-DIP).

Q: Is the MAX7219ENG+ suitable for new product designs?

A: Yes. The MAX7219ENG+ is in active production status with current compliance certifications, making it the appropriate choice for new designs requiring an 8-digit LED display driver with 4-wire serial interface.
