SN74LVC1G17DBV3 Equivalent & Substitute Parts

Part Overview

The SN74LVC1G17DBV3 is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, designed for single-element, single-bit buffering applications with push-pull output configuration. This device operates across a wide supply voltage range of 1.65V to 5.5V and is housed in a SOT-23-5 surface mount package. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity). Substitute parts are identified when equivalent electrical performance, package compatibility, and operational specifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC1G17DBV3 are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Critical Matching Parameters:

• Logic Type: Buffer, Non-Inverting (identical function)
• Number of Elements: 1 (single buffer element)
• Number of Bits per Element: 1 (single-bit operation)
• Output Type: Push-Pull (identical output configuration)
• Current - Output High, Low: 32mA, 32mA (identical drive capability)
• Voltage - Supply: 1.65V ~ 5.5V (identical supply range)
• Operating Temperature: -40°C ~ 125°C (TA) (identical thermal range)
• Mounting Type: Surface Mount (identical mounting method)
• Package / Case: SC-74A, SOT-753 (identical physical package)
• Series: 74LVC (same logic family)

Substitute parts maintain identical electrical specifications and package footprints, ensuring direct functional replacement without circuit redesign. Variations in packaging format (Tape & Reel versus Bulk) and manufacturer do not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—SN74LVC1G34DBVT and 74LVC1G34GV,125—are qualified equivalents for the SN74LVC1G17DBV3 based on identical electrical specifications and package compatibility.

SN74LVC1G34DBVT (Texas Instruments): This substitute maintains Texas Instruments manufacturer continuity and is supplied in Tape & Reel format. It carries ROHS3 compliance certification and REACH Unaffected status, with documented ECCN and HTSUS classifications. This option is suitable for applications requiring consistent manufacturer sourcing and documented regulatory compliance.

74LVC1G34GV,125 (NXP Semiconductors): This substitute is supplied in Bulk packaging format and offers significantly higher inventory availability (29,761 pieces versus 1,459 pieces for the Texas Instruments alternative). It maintains identical electrical performance and package specifications. This option is suitable for high-volume applications where supply availability and cost optimization are primary considerations.

Both parts are Active status products within the 74LVC logic family, ensuring long-term availability and design stability. Selection between substitutes should be based on procurement requirements, packaging format preference, and supply chain strategy rather than electrical performance, as all three parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC1G34DBVT directly replace SN74LVC1G17DBV3 without circuit modification?

A: Yes. Both parts are non-inverting buffers with identical electrical specifications (1 element, 1 bit, 32mA output drive, 1.65V–5.5V supply range, -40°C to 125°C operating temperature) and identical package footprints (SOT-23-5/SC-74A). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the two substitute parts?

A: SN74LVC1G34DBVT is manufactured by Texas Instruments and supplied in Tape & Reel format. 74LVC1G34GV,125 is manufactured by NXP Semiconductors and supplied in Bulk format. Electrical specifications and package dimensions are identical. The primary differences are manufacturer, packaging format, and inventory availability.

Q: Are there packaging format considerations when selecting a substitute?

A: Yes. The main part (SN74LVC1G17DBV3) is specified as Prototype packaging. SN74LVC1G34DBVT is supplied as Tape & Reel (TR), suitable for automated assembly. 74LVC1G34GV,125 is supplied in Bulk format. Packaging format selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Does the NXP substitute (74LVC1G34GV,125) have the same compliance certifications as the Texas Instruments parts?

A: The NXP part maintains MSL Level 1 (Unlimited) and REACH Unaffected status. RoHS3 compliance is not specified in the provided data for the NXP part. If RoHS3 certification is a design requirement, the Texas Instruments substitute (SN74LVC1G34DBVT) is the documented compliant option.

Q: Can I use these substitutes interchangeably in production?

A: Yes, provided packaging format and compliance requirements are met. Both substitutes are electrically and mechanically equivalent. Verify that the selected packaging format (Tape & Reel or Bulk) aligns with your assembly process before implementation.
