DM74ALS04BSJ Equivalent & Substitute Parts

Part Overview

The DM74ALS04BSJ is a 6-channel inverter logic IC manufactured by onsemi in a 14-SOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 74ALS04 series provides standard inverter functionality with TTL-compatible logic levels and is widely used in digital logic circuits requiring signal inversion across multiple channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DM74ALS04BSJ is determined by the following critical parameters:

• Logic Function: All substitutes must be 6-channel inverters with 1 input per channel
• Electrical Specifications: Supply voltage (4.5V ~ 5.5V), output current (400µA, 8mA), input logic levels, and propagation delay (11ns @ 5V, 50pF) must match or be compatible
• Operating Temperature Range: 0°C ~ 70°C
• Mounting Type: Surface mount only
• Base Product Number: 74ALS04 series

Substitute parts are grouped into two categories:

Direct Substitutes (pin-compatible, identical package):

• SN74ALS04BNS (Texas Instruments, 14-SO package)
• SN74ALS04BNSR (Texas Instruments, 14-SO package, Tape & Reel)

Similar Substitutes (pin-compatible, alternative package variant):

• SN74ALS04BD (Texas Instruments, 14-SOIC package, 0.154" width)
• SN74ALS04BDR (Texas Instruments, 14-SOIC package, 0.154" width, Cut Tape)

All substitutes maintain the same logic function, electrical performance, and thermal operating range as the original part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Package Footprint - 0.209" Width):

SN74ALS04BNSR is the preferred choice. This Texas Instruments part is active in production status, ROHS3 compliant, and available in Tape & Reel packaging suitable for automated assembly. It maintains identical electrical specifications and package dimensions to the original DM74ALS04BSJ, ensuring drop-in compatibility without PCB redesign.

SN74ALS04BNS is an alternative direct replacement with identical specifications but carries Last Time Buy status, indicating limited future availability.

For Alternative Package Variant (Narrower Package - 0.154" Width):

SN74ALS04BDR is suitable when PCB space constraints permit use of the narrower 14-SOIC package variant. This part is active in production and ROHS3 compliant. The narrower package footprint (0.154" versus 0.209" width) requires PCB layout modification but maintains full electrical compatibility.

SN74ALS04BD is available with identical specifications but carries Last Time Buy status.

Compliance Considerations:

All Texas Instruments substitutes are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements. The original onsemi part carries obsolete status, making transition to an active substitute necessary for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS04BNS be used as a direct replacement for DM74ALS04BSJ?

A: Yes. Both parts share identical electrical specifications, operating temperature range, and the same 14-SOIC package footprint (0.209" width). The primary difference is that SN74ALS04BNS has slightly different input logic level thresholds (0.4V ~ 0.5V low versus 0.8V), which remains within TTL compatibility margins. No PCB modifications are required.

Q: What is the difference between SN74ALS04BNS and SN74ALS04BNSR?

A: Both parts are electrically identical Texas Instruments 74ALS04 inverters with the same package and specifications. The difference is packaging format: BNS is supplied in Tube packaging, while BNSR is supplied in Tape & Reel (TR) format. BNSR is preferred for automated assembly processes. SN74ALS04BNSR also carries Active product status, ensuring continued availability.

Q: Can I use SN74ALS04BD or SN74ALS04BDR if my PCB is designed for the 0.209" package width?

A: No. SN74ALS04BD and SN74ALS04BDR use a narrower 14-SOIC package (0.154" width) that is not footprint-compatible with the original 0.209" width design. These parts require PCB layout modification and are suitable only when space constraints justify redesign.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Texas Instruments substitutes (SN74ALS04BNS, SN74ALS04BNSR, SN74ALS04BD, SN74ALS04BDR) are ROHS3 compliant. The original onsemi DM74ALS04BSJ does not specify RoHS status.

Q: What is the difference between Last Time Buy and Active product status?

A: Active status indicates the part is in current production with indefinite availability. Last Time Buy status indicates the manufacturer has announced end-of-life, with a final order deadline after which the part will no longer be manufactured. For long-term applications, select parts with Active status.

Q: Do all these parts have the same propagation delay?

A: Yes. All parts in this comparison maintain 11ns maximum propagation delay at 5V with 50pF load, ensuring identical timing performance in digital logic circuits.
