Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC1G99GD,125 is determined by strict equivalence across the following critical parameters:

• Logic Function: Configurable multiple function gate with identical circuit count (1) and input count (4)
• Output Characteristics: Tri-state output with matching current specifications (32mA high and low)
• Electrical Performance: Supply voltage range 1.65V ~ 5.5V and operating temperature range -40°C ~ 125°C
• Series Compatibility: 74LVC logic family designation
• Compliance Standards: ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification

The SN74LVC1G99DCUR from Texas Instruments meets all these criteria and is classified as an active product, providing long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC1G99DCUR is the direct functional equivalent for the obsolete 74LVC1G99GD,125. Both parts share identical electrical specifications, logic functionality, and compliance certifications (ROHS3, REACH unaffected, EAR99). The primary distinction is product status: the Texas Instruments variant is actively manufactured and supported, ensuring availability for new designs and replacement applications.

Package differences exist between the two parts (8-XFDFN versus 8-VFSOP), requiring PCB layout verification during substitution. Both packages are surface-mount configurations with equivalent pin counts and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC1G99DCUR directly replace the 74LVC1G99GD,125 in existing designs?

A: Electrical and functional compatibility is complete. PCB layout modification is necessary due to package differences (8-XFDFN to 8-VFSOP). Pin assignments and electrical characteristics are identical.

Q: Why is the 74LVC1G99GD,125 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SN74LVC1G99DCUR provides equivalent functionality with active manufacturing support.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99. Compliance profiles are identical.

Q: What is the primary consideration when substituting these parts?

A: Package footprint compatibility is the critical design consideration. The 8-XFDFN package (Nexperia) differs from the 8-VFSOP package (Texas Instruments), requiring PCB redesign or adapter solutions.

Q: Is the supply voltage range identical between both parts?

A: Yes. Both parts operate across 1.65V ~ 5.5V supply voltage and -40°C ~ 125°C temperature range with identical output current specifications.
