Substitute Part Grouping Explanation

Substitution of the SN74LVC841ADGVR is determined by strict equivalence across the following critical parameters:

• Base product number (74LVC841 series)
• Logic type (D-Type Transparent Latch)
• Circuit configuration (10:10)
• Output type (Tri-State)
• Electrical specifications (voltage supply, propagation delay, output current)
• Operating temperature range
• RoHS and environmental compliance status

The SN74LVC841APWR qualifies as a direct substitute based on identical electrical performance and functional characteristics. The primary distinction lies in packaging format and product status, with the substitute offering active availability through standard tape and reel distribution.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC841APWR directly replace the SN74LVC841ADGVR in existing designs?

A: Yes. Both components share identical electrical specifications, logic function, and operating parameters. The substitute maintains the same supply voltage range, propagation delay, output current ratings, and operating temperature range.

Q: What is the difference between the 24-TFSOP and 24-TSSOP packages?

A: Both packages maintain identical physical dimensions (0.173" width, 4.40mm) and pin configurations. The primary distinction is in manufacturing process and supplier designation. Both are surface-mount packages suitable for automated assembly.

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

A: No. Both components carry identical RoHS3 compliance status, moisture sensitivity level 1 (unlimited), and REACH unaffected classification. Environmental and regulatory certifications are equivalent.

Q: Why is the main part listed as obsolete?

A: The SN74LVC841ADGVR has been discontinued by Texas Instruments. The SN74LVC841APWR remains in active production and represents the current manufacturing variant of the same base product.

Q: Are the propagation delay and output current specifications identical?

A: Yes. Both parts specify 2.7ns propagation delay and 24mA output current for both high and low states, ensuring equivalent timing and drive characteristics in circuit applications.
