Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AS832BDW is determined by strict equivalence across the following parameters:

• Logic function: 6-channel, 2-input OR Gate configuration
• Electrical specifications: 4.5V ~ 5.5V supply voltage, 48mA output current, 6.3ns propagation delay
• Package format: 20-SOIC surface mount package with identical physical dimensions
• Compliance certifications: ROHS3 Compliant, REACH Unaffected status
• Series compatibility: 74AS logic family

The SN74AS832BDWR qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format: the substitute uses Tape & Reel (TR) configuration instead of Tube, and maintains Active product status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS832BDWR is a direct functional and electrical equivalent to the SN74AS832BDW. Selection between these parts should be based on:

• Product lifecycle status: The SN74AS832BDWR maintains Active status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the SN74AS832BDW.
• Packaging requirements: The SN74AS832BDW is supplied in Tube packaging, while the SN74AS832BDWR is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments.
• Inventory availability: The SN74AS832BDWR has 2800 units in stock versus 769 units for the SN74AS832BDW, providing greater supply security.
• Compliance: Both parts maintain identical ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory compliance in all applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS832BDWR be used as a direct replacement for the SN74AS832BDW in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same 20-SOIC package dimensions, supply voltage range, output current specifications, propagation delay, and operating temperature range. No circuit modifications are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies individual components in a plastic tube, suitable for manual assembly or small-quantity applications. Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment used in high-volume manufacturing.

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

A: No. Both the SN74AS832BDW and SN74AS832BDWR maintain identical ROHS3 Compliant and REACH Unaffected certifications. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts.

Q: Why is the SN74AS832BDW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production runs are planned. The SN74AS832BDWR, with Active status, represents the recommended long-term sourcing option.

Q: Do these parts require different handling or storage procedures?

A: Both parts have identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both components.
