SN74ALS05ANS Equivalent & Substitute Parts

Part Overview

The SN74ALS05ANS is a 6-channel inverter IC with open collector outputs manufactured by Texas Instruments in the 74ALS logic series. This device features 6 independent inverter circuits in a 14-SO surface mount package and operates across a 4.5V to 5.5V supply voltage range. The SN74ALS05ANS is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure continued design support, maintain supply chain continuity, and transition to active product alternatives within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ALS05ANS is determined by the following critical parameters:

Core Functional Parameters:

• Logic type (Inverter)
• Number of circuits (6 channels)
• Open collector output configuration
• Supply voltage range (4.5V ~ 5.5V)
• Propagation delay (54ns @ 5V, 50pF)
• Operating temperature range (0°C ~ 70°C)

Physical & Compliance Parameters:

• Package type (14-SOIC)
• Surface mount mounting type
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The SN74ALS05ANSR qualifies as a direct substitute based on matching all core functional parameters and physical specifications. The primary distinction is packaging format (Tape & Reel versus individual units) and product status transition (Last Time Buy to Active).

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS05ANSR is the direct substitute for the SN74ALS05ANS. Both devices are manufactured by Texas Instruments and share identical electrical specifications, timing characteristics, and physical package dimensions. The SN74ALS05ANSR maintains active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy designation of the SN74ALS05ANS.

Both parts comply with ROHS3 requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, making them suitable for standard manufacturing and storage conditions. The functional equivalence is complete across all provided electrical parameters, including supply voltage, logic levels, propagation delay, and output current specifications.

The selection between these parts should be based on procurement requirements: the SN74ALS05ANS for existing inventory drawdown, and the SN74ALS05ANSR for new designs and ongoing production due to its active status and Tape & Reel packaging format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS05ANSR directly replace the SN74ALS05ANS in existing designs?

A: Yes. The SN74ALS05ANSR is electrically and mechanically equivalent to the SN74ALS05ANS. All functional parameters, including logic type, circuit count, output configuration, supply voltage, timing characteristics, and package dimensions are identical. No design modifications are required.

Q: What is the difference between SN74ALS05ANS and SN74ALS05ANSR?

A: The primary differences are product status and packaging format. The SN74ALS05ANS is Last Time Buy status with individual unit packaging, while the SN74ALS05ANSR is Active status with Tape & Reel packaging. Electrically and functionally, both devices are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74ALS05ANS and SN74ALS05ANSR are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What does Last Time Buy status mean for the SN74ALS05ANS?

A: Last Time Buy indicates that the SN74ALS05ANS is at end-of-life. Texas Instruments will no longer manufacture this part after existing inventory is depleted. The SN74ALS05ANSR, with Active status, is the recommended long-term alternative.

Q: Are there any timing or performance differences between these parts?

A: No. Both devices specify identical maximum propagation delay of 54ns at 5V with 50pF load, input logic levels, and output current characteristics.

Q: What is the package specification for both parts?

A: Both parts use the 14-SOIC package with 0.209" (5.30mm) width, suitable for surface mount assembly on standard PCBs.
