DM74ALS04BM Equivalent & Substitute Parts

Part Overview

The DM74ALS04BM is a 6-channel inverter logic IC manufactured by onsemi in a 14-SOIC surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The DM74ALS04BM operates within the 74ALS logic family standard, which defines specific electrical and mechanical parameters that determine valid substitution candidates.

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS04BM are classified into two categories based on electrical and mechanical parameter alignment:

Direct Substitutes maintain identical electrical specifications and package dimensions. These parts satisfy all critical parameters: 6-channel inverter configuration, 1 input per channel, 4.5V–5.5V supply voltage, 400µA/8mA output current ratings, 0.8V/2V input logic thresholds, 11ns maximum propagation delay at 5V with 50pF load, and 0°C–70°C operating temperature range. Direct substitutes include SN74ALS04BD and SN74ALS04BDR, both manufactured by Texas Instruments.

Similar Substitutes maintain all electrical specifications but differ in package dimensions. SN74ALS04BNSR operates identically to the main part across all electrical parameters but uses a 14-SO package with 5.30mm width instead of the standard 14-SOIC 3.90mm width. This dimensional difference may affect PCB layout compatibility.

Engineering Selection Recommendations

For direct replacement with identical PCB footprint compatibility: Select SN74ALS04BDR (Texas Instruments, Active status). This part maintains all electrical parameters and package dimensions of the DM74ALS04BM while offering active product status and ROHS3 compliance. Cut Tape packaging supports both prototype and production volumes.

For applications with packaging flexibility: SN74ALS04BD (Texas Instruments, Last Time Buy status) provides identical electrical and dimensional specifications but with Tube packaging. This option remains available but carries Last Time Buy status, indicating limited future availability.

For high-volume applications with package dimension tolerance: SN74ALS04BNSR (Texas Instruments, Active status) delivers all electrical equivalence with Tape & Reel packaging suitable for automated assembly. The 14-SO package with 5.30mm width differs from the standard 3.90mm 14-SOIC, requiring PCB layout verification before implementation.

All substitute parts maintain REACH Unaffected and EAR99 export classification status consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS04BNSR be used as a direct drop-in replacement for DM74ALS04BM?

A: SN74ALS04BNSR is electrically equivalent but uses a 14-SO package with 5.30mm width versus the 14-SOIC 3.90mm width of the DM74ALS04BM. PCB footprint compatibility must be verified before substitution. If the PCB is designed for 14-SOIC spacing, SN74ALS04BDR or SN74ALS04BD are required for direct compatibility.

Q: What is the difference between SN74ALS04BD and SN74ALS04BDR?

A: Both parts are electrically and dimensionally identical. The difference is packaging format: SN74ALS04BD uses Tube packaging, while SN74ALS04BDR uses Cut Tape packaging. SN74ALS04BDR carries Active product status, whereas SN74ALS04BD is Last Time Buy. For new designs, SN74ALS04BDR is preferred.

Q: Why is the DM74ALS04BM marked as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Substitute parts from active manufacturers ensure continued supply chain availability for production and maintenance applications.

Q: Are all substitute parts RoHS compliant?

A: All Texas Instruments substitute parts (SN74ALS04BD, SN74ALS04BDR, SN74ALS04BNSR) are ROHS3 compliant. The original DM74ALS04BM RoHS status was not specified in available documentation.

Q: What packaging format should I select for production assembly?

A: SN74ALS04BDR (Cut Tape) is optimized for automated pick-and-place assembly. SN74ALS04BNSR (Tape & Reel) supports high-volume production. SN74ALS04BD (Tube) is suitable for lower-volume or manual assembly processes.
