74LVC1G99DP,125 Equivalent & Substitute Parts

Part Overview

The 74LVC1G99DP,125 is a configurable multiple function logic gate IC manufactured by Nexperia USA Inc. in the 74LVC series. This single-circuit, 4-input device features tri-state output capability and operates across a wide supply voltage range of 1.65V to 5.5V, making it suitable for mixed-voltage applications. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are necessary when the 8-TSSOP package variant is unavailable or when alternative packaging formats better suit specific board layout requirements while maintaining identical electrical functionality.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical specifications with the main part 74LVC1G99DP,125. Substitution eligibility is determined by the following criteria:

• Base product number: 74LVC1G99
• Logic type: Configurable Multiple Function
• Circuit and input configuration: 1 circuit, 4 inputs
• Output type: Tri-State
• Current ratings: 32mA output high and low
• Supply voltage range: 1.65V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C
• Compliance: ROHS3, REACH Unaffected, MSL 1

Substitute parts differ only in package format and manufacturer designation. The primary variants are 8-LSSOP (8-MSOP 0.110" width) and 8-VFSOP (0.091" width) packages, offered by Texas Instruments with different packaging options (Tape & Reel or Cut Tape).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance and REACH Unaffected status, meeting the same regulatory requirements as the main part. Selection between substitutes should be based on:

Package footprint compatibility: The 8-TSSOP package (0.118" width) of the main part differs from the 8-LSSOP (0.110" width) and 8-VFSOP (0.091" width) variants. PCB layout and routing requirements may necessitate selection of a specific package format.

Packaging format: Choose between Tape & Reel for high-volume production or Cut Tape & Digi-Reel for lower-volume applications based on assembly process requirements.

Inventory availability: Texas Instruments variants offer higher stock levels, with SN74LVC1G99DCTR providing the largest available quantity at 10,666 pieces.

All substitute parts maintain identical electrical performance and thermal characteristics, ensuring direct functional equivalence within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC1G99DCTR be used as a direct replacement for 74LVC1G99DP,125?

A: Yes, SN74LVC1G99DCTR is electrically equivalent. However, the package footprint differs: 8-LSSOP (0.110" width) versus 8-TSSOP (0.118" width). PCB layout modifications may be required to accommodate the different pin pitch and body dimensions.

Q: What is the difference between the 8-LSSOP and 8-VFSOP package variants?

A: The 8-LSSOP package has a body width of 0.110" (2.80mm), while the 8-VFSOP package is narrower at 0.091" (2.30mm). Both maintain the same pin count and electrical specifications. The 8-VFSOP variant is suitable for space-constrained applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with REACH Unaffected status, matching the compliance profile of the main part.

Q: What packaging options are available for the Texas Instruments variants?

A: Texas Instruments offers both Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging options. SN74LVC1G99DCUR and SN74LVC1G99DCUT use the 8-VFSOP package, while SN74LVC1G99DCTR and SN74LVC1G99DCTT use the 8-LSSOP package.

Q: Do all parts operate at the same supply voltage and temperature range?

A: Yes, all parts operate at 1.65V to 5.5V supply voltage with an operating temperature range of -40°C to 125°C. Output current specifications are identical at 32mA for both high and low states.
