SN74LVC2G38YZPR Equivalent & Substitute Parts

Part Overview

The SN74LVC2G38YZPR is a NAND Gate IC manufactured by Texas Instruments, featuring 2 channels with 2 inputs per channel in an 8-DSBGA package. This device implements open drain logic gates with a supply voltage range of 1.65V to 5.5V, making it suitable for mixed-voltage applications. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LVC2G38YZPR is determined by strict equivalence across the following critical parameters:

• Logic function: NAND Gate with identical circuit count (2) and input configuration (2 inputs per channel)
• Electrical characteristics: Supply voltage range (1.65V ~ 5.5V), quiescent current (10 µA max), output current (32mA), input logic levels, and propagation delay (3.9ns @ 5V, 50pF)
• Features: Open drain output configuration
• Operating temperature range: -40°C ~ 85°C
• Compliance: ROHS3 compliant, MSL 1, REACH unaffected
• Base product number: 74LVC2G38

Substitute parts must maintain identical electrical performance and functional behavior. Package variations are permitted when the base product number and electrical specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC2G38YZPR is obsolete and requires replacement. Two active alternatives are available:

SN74LVC2G38DCTR (Texas Instruments) provides complete electrical and functional equivalence with all parameters matching the original part. This substitute is manufactured by the original supplier and maintains ROHS3 compliance. The primary difference is the package format (SM8 versus 8-DSBGA), which requires PCB layout modification. This part is recommended for applications where Texas Instruments sourcing is preferred and board redesign is feasible.

74LVC2G38GT,115 (NXP Semiconductors) shares the base product number and logic function. Complete electrical parameter data is not provided in available documentation. This part is recommended only when NXP sourcing is mandated or when the SM8 package is unavailable from Texas Instruments.

Selection between these substitutes depends on supply chain requirements, PCB layout constraints, and manufacturer preference. Both parts are active and available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC2G38DCTR directly replace the SN74LVC2G38YZPR without circuit modification?

A: The SN74LVC2G38DCTR is electrically equivalent and functionally identical. However, the package change from 8-DSBGA to SM8 (8-LSSOP/8-MSOP) requires PCB layout modification. Pin assignments must be verified against both datasheets before implementation.

Q: What is the primary reason for substitution?

A: The SN74LVC2G38YZPR is obsolete. Active alternatives with identical electrical specifications are available to ensure continued product support and supply chain continuity.

Q: Are there differences in operating temperature range between the main part and substitutes?

A: The SN74LVC2G38DCTR maintains the identical operating temperature range of -40°C to 85°C. Temperature specifications for the 74LVC2G38GT,115 are not provided in available data.

Q: What compliance certifications apply to these parts?

A: The SN74LVC2G38YZPR and SN74LVC2G38DCTR are both ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status. The 74LVC2G38GT,115 maintains MSL 1 classification.

Q: How do package differences affect circuit design?

A: The 8-DSBGA package (original) and SM8 package (SN74LVC2G38DCTR substitute) have different footprints and pin layouts. PCB redesign is required for package substitution. The 74LVC2G38GT,115 package format is not specified in available documentation.

Q: Are electrical performance characteristics identical across all substitutes?

A: The SN74LVC2G38DCTR provides complete electrical equivalence with matching supply voltage, quiescent current, output current, input logic levels, and propagation delay specifications. Complete electrical data for the 74LVC2G38GT,115 is not available.
