SN74ALS1034D Equivalent & Substitute Parts

Part Overview

The SN74ALS1034D is a Buffer, Non-Inverting logic IC manufactured by Texas Instruments, featuring 6 elements with 1 bit per element and 3-state output capability. Housed in a 14-SOIC surface mount package, this component operates within a 4.5V to 5.5V supply voltage range and is rated for 0°C to 70°C operating temperature.

The SN74ALS1034D carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status necessitates identification of equivalent substitute parts to ensure design continuity and procurement availability for new projects or production runs.

Substitute Part Grouping Explanation

Substitution of the SN74ALS1034D is determined by strict equivalence across the following critical parameters:

• Logic Function: Buffer, Non-Inverting configuration with identical element and bit-per-element count (6 elements, 1 bit per element)
• Output Characteristics: 3-state output with matching current specifications (15mA high, 24mA low)
• Electrical Specifications: Identical supply voltage range (4.5V ~ 5.5V) and operating temperature range (0°C ~ 70°C)
• Package Compatibility: 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating maintained across all substitutes

The SN74ALS1034DR qualifies as a direct substitute based on complete parameter alignment. The primary distinction is packaging format: the original part uses Tube packaging, while the substitute uses Tape & Reel (TR) format. Both formats contain identical die and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS1034DR is the direct substitute for the SN74ALS1034D. Both parts are manufactured by Texas Instruments and maintain identical electrical and functional specifications. The SN74ALS1034DR carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and reliability requirements. The substitution involves only a packaging format change from Tube to Tape & Reel, which does not affect component performance or circuit functionality. This change is transparent to circuit design and operation.

For new designs or production transitions, the SN74ALS1034DR is the recommended selection due to its Active status and equivalent technical specifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS1034DR be used as a direct replacement for the SN74ALS1034D in existing designs?

A: Yes. The SN74ALS1034DR is electrically and functionally identical to the SN74ALS1034D. All electrical parameters, logic function, output characteristics, and package dimensions are equivalent. The only difference is the packaging format (Tube versus Tape & Reel), which does not affect circuit performance.

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

A: Tube and Tape & Reel are different packaging and delivery formats for the same component. Tube packaging is used for lower-volume orders and manual handling, while Tape & Reel format is optimized for automated assembly processes and higher-volume production. The internal component and electrical specifications remain identical.

Q: Why is the SN74ALS1034D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued active production of this part number. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. The SN74ALS1034DR, with Active status, is the recommended alternative for new projects.

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

A: No. Both the SN74ALS1034D and SN74ALS1034DR maintain identical ROHS3 compliance and MSL Level 1 ratings. Environmental and reliability certifications are equivalent.

Q: Can I mix Tube and Tape & Reel packaging in the same production run?

A: Yes. Since both packaging formats contain identical components with identical electrical specifications, they can be used interchangeably in the same circuit design and production environment. Packaging format selection is typically driven by assembly process requirements and volume considerations.
