Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS11AN is determined by strict equivalence across the following parameters:

• Logic function: 3-channel AND gate with 3 inputs per channel
• Electrical specifications: 4.5V to 5.5V supply voltage, 400µA output high current, 8mA output low current
• Logic thresholds: 0.8V input low, 2V input high
• Timing: 13ns maximum propagation delay at 5V with 50pF load
• Operating temperature range: 0°C to 70°C
• Physical form factor: 14-pin DIP package with 0.300" (7.62mm) pitch
• Series classification: 74ALS logic family

The SN74ALS11AN from Texas Instruments meets all these parameters identically, establishing it as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS11AN from Texas Instruments is the direct parametric equivalent for the obsolete DM74ALS11AN. Both parts share identical electrical characteristics, logic function, timing specifications, and physical packaging. The primary distinction is product status: the onsemi part is obsolete while the Texas Instruments variant remains in active production.

For new designs or component replacement in existing systems, the SN74ALS11AN is the appropriate selection. The active product status ensures ongoing availability and supply chain continuity. Both parts are REACH Unaffected and classified under ECCN EAR99, maintaining equivalent regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS11AN directly replace the DM74ALS11AN in existing circuits?

A: Yes. The SN74ALS11AN is a parametric equivalent with identical electrical specifications, logic function, timing characteristics, and 14-DIP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The DM74ALS11AN is classified as obsolete, indicating onsemi has discontinued production. The SN74ALS11AN remains in active production by Texas Instruments, ensuring component availability for procurement and future system support.

Q: Are there packaging differences between these parts?

A: Both parts use 14-pin DIP packaging with 0.300" (7.62mm) pitch. The onsemi part specifies 14-MDIP while Texas Instruments specifies 14-PDIP; both designations refer to the same physical form factor and are mechanically and electrically compatible.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: 3-channel AND gate configuration, 3 inputs per channel, 4.5V to 5.5V supply voltage, 400µA/8mA output current ratings, 0.8V/2V logic thresholds, 13ns propagation delay at 5V with 50pF load, 0°C to 70°C operating temperature, and 14-DIP package form factor.

Q: Are there compliance or certification differences?

A: Both parts are REACH Unaffected and carry EAR99 classification. The Texas Instruments part includes RoHS3 compliance certification, while the onsemi part does not specify RoHS status. Both maintain equivalent regulatory standing for industrial applications.
