Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC1G97YZPRB is determined by the following critical parameters that must remain consistent across equivalent parts:

Core Functional Parameters:

• Base product number: 74LVC1G97
• Logic type: Configurable Multiple Function
• Number of circuits: 1
• Number of inputs: 3
• Output type: Single-Ended
• Output current capability: 32mA / 32mA
• Supply voltage range: 1.65V ~ 5.5V

Compliance & Environmental Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Manufacturer: Texas Instruments

The SN74LVC1G97DSFR qualifies as a manufacturer-recommended substitute because it maintains identical functional specifications, electrical characteristics, and compliance certifications. Differences in package type (6-SON versus 6-DSBGA), Schmitt trigger input availability, and operating temperature range do not preclude substitution when the application requirements align with the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC1G97DSFR is the manufacturer-recommended substitute for the obsolete SN74LVC1G97YZPRB. This substitute maintains active product status with Texas Instruments, ensuring ongoing availability and supply chain support.

Substitution Basis:

The SN74LVC1G97DSFR preserves all critical functional and electrical parameters: identical logic configuration, circuit count, input count, output current specifications, and supply voltage range. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Considerations for Implementation:

Package geometry differs between the main part (6-DSBGA, 1.39x.89mm) and the substitute (6-SON, 1x1mm). PCB layout modifications are required to accommodate the different package footprint. The substitute part operates across an extended temperature range (-40°C to 125°C versus -40°C to 85°C), providing additional thermal margin. The absence of Schmitt trigger input in the substitute part requires verification that application requirements do not depend on this feature.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC1G97DSFR directly replace the SN74LVC1G97YZPRB without design changes?

A: Electrical substitution is valid; however, PCB layout modification is required due to package geometry differences. The main part uses 6-DSBGA packaging (1.39x.89mm), while the substitute uses 6-SON packaging (1x1mm). Footprint redesign is necessary.

Q: What is the significance of the Schmitt trigger input difference?

A: The main part includes Schmitt trigger input capability; the substitute does not. If the application circuit relies on Schmitt trigger hysteresis for noise immunity or signal conditioning, the substitute part may not provide equivalent performance. Verify that input signal characteristics are compatible with standard CMOS input thresholds.

Q: Why is the SN74LVC1G97YZPRB classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The SN74LVC1G97DSFR is the active equivalent, indicating that Texas Instruments has transitioned production to this part number while maintaining functional compatibility.

Q: Are there differences in supply voltage or output current between these parts?

A: No. Both parts operate across the identical supply voltage range (1.65V to 5.5V) and deliver identical output current specifications (32mA high and low). Electrical performance in these parameters is equivalent.

Q: What is the impact of the extended operating temperature range in the substitute part?

A: The SN74LVC1G97DSFR operates from -40°C to 125°C, compared to -40°C to 85°C for the main part. This extended range provides additional thermal margin and may improve reliability in high-temperature environments. No negative impact occurs if the application operates within the main part's original temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74LVC1G97YZPRB and SN74LVC1G97DSFR are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
