DM74ALS05AN Equivalent & Substitute Parts

Part Overview

The DM74ALS05AN is a 6-channel inverter logic IC with open collector outputs, manufactured by onsemi in a 14-MDIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates within a 4.5V to 5.5V supply voltage range and is designed for through-hole mounting applications in legacy and maintenance-level designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS05AN are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution logic is determined by the following parameters:

• Logic Type: Inverter (6-channel, 1-input per channel)
• Features: Open Collector output configuration
• Voltage Supply Range: 4.5V ~ 5.5V
• Input Logic Levels: Low 0.8V, High 2V
• Package Type: 14-DIP through-hole mounting
• Base Product Number: 74ALS05 series

Direct substitutes maintain identical electrical specifications and package dimensions. Similar substitutes may exhibit enhanced performance characteristics (faster propagation delay, higher output current) while maintaining functional compatibility within the same logic family and package footprint.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS05AN (Direct Substitute): This Texas Instruments part is the primary equivalent for the obsolete DM74ALS05AN. It maintains identical electrical specifications, logic configuration, and package dimensions. The SN74ALS05AN carries Active product status and ROHS3 compliance, making it suitable for new designs and legacy system maintenance. This part is the recommended first choice for direct replacement.

SN74ALS1005N (Similar Substitute): This Texas Instruments variant offers enhanced performance characteristics within the same 14-DIP package footprint. The SN74ALS1005N provides faster propagation delay (30ns versus 54ns) and higher output current capability (24mA versus 8mA). This part is functionally compatible but operates under a different base product number (74ALS1005). Selection of this variant should be based on system performance requirements and design margin considerations. The SN74ALS1005N also carries Active product status and ROHS3 compliance.

Both substitute parts maintain compatibility with the original DM74ALS05AN in terms of supply voltage range, input logic levels, operating temperature, and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS05AN be used as a direct replacement for the DM74ALS05AN?

A: Yes. The SN74ALS05AN is a direct substitute. Both parts share identical electrical specifications, including supply voltage (4.5V ~ 5.5V), input logic levels (0.8V low, 2V high), output current (8mA), propagation delay (54ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C). The 14-DIP package dimensions are identical, enabling pin-for-pin replacement.

Q: What is the difference between the SN74ALS05AN and SN74ALS1005N?

A: Both parts are 6-channel inverters with open collector outputs in 14-DIP packages. The SN74ALS1005N offers improved performance: propagation delay of 30ns (versus 54ns) and output current of 24mA (versus 8mA). The SN74ALS1005N operates under a different base product number (74ALS1005 versus 74ALS05). Electrical compatibility is maintained across supply voltage, input logic levels, and operating temperature ranges.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the 14-DIP (0.300", 7.62mm) through-hole package. Pin spacing and mounting footprint are identical, allowing direct socket replacement without PCB modification.

Q: What compliance certifications apply to the substitute parts?

A: Both Texas Instruments substitutes (SN74ALS05AN and SN74ALS1005N) are ROHS3 compliant and REACH unaffected. The original DM74ALS05AN is REACH unaffected; RoHS status was not specified in the original documentation.

Q: Why is the DM74ALS05AN classified as obsolete?

A: The DM74ALS05AN is an older logic component from onsemi. Active alternatives from major manufacturers such as Texas Instruments ensure continued design support and procurement availability for applications requiring 6-channel inverter functionality with open collector outputs.
