MM5452VX LCD Driver Equivalent & Substitute Parts

Part Overview

The MM5452VX is a 7-segment LCD driver IC manufactured by Texas Instruments, designed for 4.5-digit display applications. This device operates as a serial interface LCD driver with support for 7-segment, decimal point, alphanumeric, and bar graph display configurations. The MM5452VX is classified as obsolete, making equivalent substitute parts necessary for ongoing production, maintenance, and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM5452VX is determined by strict equivalence across the following critical parameters:

• Display Driver Functionality: 7-segment LCD driver with 4.5-digit capacity
• Serial Interface Protocol: Serial communication interface requirement
• Display Configuration Support: 7-segment, decimal point, alphanumeric, and bar graph capability
• Electrical Specifications: Supply voltage range 3V ~ 10V, operating temperature -40°C ~ 85°C
• Physical Package: 44-LCC (J-Lead) form factor, 44-PLCC (16.58x16.58) footprint
• Mounting Technology: Surface mount configuration

The MM5452VX/NOPB variant qualifies as a direct substitute based on identical electrical, functional, and mechanical specifications. Packaging format differences (bulk versus tape & reel) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MM5452VX/NOPB is the direct functional equivalent of the MM5452VX. Both parts share identical electrical specifications, display driver capabilities, and physical packaging. Selection between these variants should be based on the following criteria:

MM5452VX/NOPB Advantages: This variant carries Last Time Buy status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory compliance with modern environmental standards. The ROHS3 certification indicates lead-free manufacturing and reduced hazardous substance content.

MM5452VX Considerations: The original MM5452VX is classified as obsolete and RoHS non-compliant. This variant should be reserved for legacy system maintenance or applications where RoHS compliance is not a requirement.

Packaging Format: The MM5452VX/NOPB is supplied in tape & reel format, optimized for automated assembly processes. The original MM5452VX bulk packaging may be preferred only for low-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can MM5452VX/NOPB be used as a direct replacement for MM5452VX in existing designs?

A: Yes. Both parts are electrically and functionally identical. The MM5452VX/NOPB operates across the same supply voltage range (3V ~ 10V), supports identical display configurations (7-segment, decimal point, alphanumeric, bar graph), and uses the same 44-PLCC package footprint. No circuit modifications are required.

Q: What is the difference between MM5452VX and MM5452VX/NOPB?

A: The primary differences are product status, compliance certification, and packaging format. MM5452VX/NOPB is ROHS3 compliant and supplied in tape & reel format, while MM5452VX is RoHS non-compliant and supplied in bulk. Functionally and electrically, both parts are equivalent.

Q: Are there any moisture sensitivity differences between these parts?

A: Yes. MM5452VX has MSL 2A (4 weeks storage at 30°C/60% RH), while MM5452VX/NOPB has MSL 3 (168 hours at 30°C/85% RH). Both ratings are within acceptable ranges for standard PCB assembly processes. Appropriate moisture control measures should be implemented according to the respective MSL classification during storage and handling.

Q: Is the 44-PLCC package compatible with standard PCB assembly equipment?

A: Yes. The 44-PLCC (44-pin Plastic Leaded Chip Carrier) with J-lead configuration is a standard surface mount package compatible with conventional pick-and-place assembly equipment and reflow soldering processes. The 16.58x16.58mm footprint is well-established in industrial manufacturing.

Q: Which variant should be selected for new product designs?

A: MM5452VX/NOPB is recommended for new designs due to ROHS3 compliance and Last Time Buy status, ensuring regulatory alignment and supply chain continuity. MM5452VX should be reserved for legacy system support only.
