SN74LVC3G34DCTRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC3G34DCTRG4 is a non-inverting buffer logic IC manufactured by Texas Instruments, featuring 3 elements with 1 bit per element and push-pull output configuration. This device operates across a supply voltage range of 1.65V to 5.5V and is housed in an 8-LSSOP/8-MSOP surface mount package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Equivalent parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC3G34DCTRG4 are qualified based on strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 3
• Number of Bits per Element: 1
• Output Type: Push-Pull
• Current - Output High, Low: 32mA, 32mA
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C (TA)
• Base Product Number: 74LVC3G34
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts maintain these electrical specifications. Package variations (8-LSSOP, 8-MSOP, 8-VSSOP, 8-TSSOP) are mechanically compatible within the specified footprint tolerances and represent different supplier packaging formats rather than functional differences.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SN74LVC3G34DCTR (Texas Instruments)

The SN74LVC3G34DCTR is the direct parametric equivalent from the original manufacturer. This part maintains identical electrical specifications and package dimensions while offering active product status with 6,300 units in stock. The packaging format is Cut Tape (CT) and Digi-Reel, suitable for both manual and automated assembly processes.

Secondary Substitute: 74LVC3G34DP,125 (Nexperia USA Inc.)

The 74LVC3G34DP,125 provides equivalent electrical performance with the highest inventory availability at 10,828 units. This part is supplied in Tape & Reel (TR) format and carries ROHS3 compliance certification. The 8-TSSOP package (0.118", 3.00mm Width) is mechanically compatible with standard PCB footprints designed for the 74LVC3G34 series.

Tertiary Substitute: 74LVC3G34DC,125 (NXP Semiconductors)

The 74LVC3G34DC,125 maintains full electrical equivalence with 9,200 units available. The 8-VFSOP package (0.091", 2.30mm Width) represents a narrower footprint variant. This option is suitable for space-constrained applications where the reduced package width provides layout advantages.

All three substitutes are qualified for direct replacement based on electrical parameter equivalence, regulatory compliance, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC3G34DCTR directly replace the discontinued SN74LVC3G34DCTRG4?

A: Yes. The SN74LVC3G34DCTR is a parametric equivalent with identical electrical specifications, operating temperature range, supply voltage range, output current ratings, and logic configuration. Both parts use the same base product number (74LVC3G34) and are manufactured by Texas Instruments.

Q: What are the package differences between the substitute parts?

A: The substitute parts use different surface mount package variants: 8-LSSOP/8-MSOP (0.110", 2.80mm width), 8-VFSOP (0.091", 2.30mm width), and 8-TSSOP/8-MSOP (0.118", 3.00mm width). These represent different supplier packaging formats for the same die. PCB footprint compatibility depends on the specific design; verify footprint dimensions against your board layout.

Q: Are all substitute parts RoHS compliant?

A: The SN74LVC3G34DCTR and 74LVC3G34DP,125 are explicitly ROHS3 compliant. The 74LVC3G34DC,125 RoHS status is not specified in the provided data. Verify RoHS compliance requirements with your procurement specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the main part and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute offers the best availability?

A: The 74LVC3G34DP,125 (Nexperia) offers the highest inventory with 10,828 units in stock, followed by the 74LVC3G34DC,125 (NXP) with 9,200 units, and the SN74LVC3G34DCTR (Texas Instruments) with 6,300 units.

Q: Are these parts suitable for military or aerospace applications?

A: All parts carry REACH Unaffected and EAR99 ECCN classifications. Verify specific application requirements and qualification standards with your procurement and engineering departments.
