MM5452V LCD Driver IC - Equivalent & Substitute Parts

Part Overview

The MM5452V 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 driver supporting alphanumeric and bar graph configurations. The MM5452V is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production, maintenance, and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM5452V is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Display Type: LCD
• Configuration: 7 Segment + DP, Alphanumeric and Bar Graph
• Digits or Characters: 4.5 Digits
• Interface: Serial
• Voltage Supply Range: 3V ~ 10V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 44-LCC (J-Lead)
• Mounting Type: Surface Mount

The MM5452V/NOPB qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional configuration. Differences in product status, RoHS compliance, and MSL rating reflect manufacturing timeline and regulatory updates rather than functional capability changes.

Parameter Comparison

Engineering Selection Recommendations

MM5452V (Original): This part carries obsolete status and RoHS non-compliant classification. Existing inventory of 2078 units is available; however, this part number should be considered end-of-life for new designs or long-term production commitments.

MM5452V/NOPB (Substitute): This variant maintains identical electrical and functional specifications while offering Last Time Buy status and ROHS3 compliance. The /NOPB suffix indicates lead-free manufacturing, aligning with current environmental and regulatory standards. Inventory of 1599 units is currently available. This part is the appropriate selection for applications requiring RoHS compliance or where regulatory documentation mandates lead-free components.

Both parts are functionally interchangeable at the circuit level. Selection between them should be based on regulatory requirements, compliance documentation needs, and inventory availability timelines.

Frequently Asked Questions (FAQ)

Q: Can MM5452V/NOPB be used as a direct replacement for MM5452V in existing designs?

A: Yes. Both parts are electrically and functionally identical. The /NOPB designation indicates lead-free manufacturing and RoHS3 compliance. No circuit modifications are required for substitution.

Q: What does the /NOPB suffix mean?

A: /NOPB indicates "No Plumbum" (no lead), signifying lead-free solder compatibility and RoHS3 compliance. This is a manufacturing and regulatory designation, not a functional change.

Q: Are there differences in pin configuration or package dimensions?

A: No. Both parts use the 44-LCC (J-Lead) package with identical 16.58x16.58mm dimensions. Pin assignments and mechanical compatibility are identical.

Q: What is the significance of the different MSL ratings?

A: MSL (Moisture Sensitivity Level) ratings reflect storage and handling requirements. MM5452V requires 4-week dry storage (2A), while MM5452V/NOPB requires 168-hour dry storage (3). Both are standard industrial ratings; handling procedures should follow the specific part's datasheet.

Q: Why is MM5452V marked as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued active production. MM5452V/NOPB (Last Time Buy status) represents the final manufacturing window for this product line before complete discontinuation.

Q: Can these parts be used interchangeably in new production designs?

A: Yes, provided the design accommodates the specified voltage supply range (3V ~ 10V) and operating temperature range (-40°C ~ 85°C). MM5452V/NOPB is recommended for new designs due to RoHS compliance and extended availability during the Last Time Buy period.
