Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS1032AMX are qualified based on the following criteria:

• Logic function: 4-channel 2-input OR gate
• Supply voltage range: 4.5V ~ 5.5V
• Input logic levels: Low 0.8V, High 2V
• Operating temperature range: 0°C ~ 70°C
• Package type: 14-SOIC surface mount
• Series classification: 74ALS

The substitute parts SN74ALS32D and SN74ALS32DR, both manufactured by Texas Instruments, meet all these electrical and mechanical requirements. Both parts maintain identical logic function, voltage specifications, input logic levels, and temperature operating range. The primary differences between substitutes relate to product status and packaging format (Tube versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, SN74ALS32DR is the preferred substitute. This part carries Active product status from Texas Instruments, ensuring long-term availability and supply chain stability. The SN74ALS32DR is ROHS3 compliant and supplied in Tape & Reel packaging, which is standard for automated assembly processes.

SN74ALS32D serves as a secondary substitute option, maintaining identical electrical specifications and 14-SOIC package compatibility. This part is classified as Last Time Buy, indicating limited future availability.

Both Texas Instruments substitutes are functionally equivalent to the DM74ALS1032AMX within the specified electrical and mechanical parameters. The output current specifications differ between the original part and substitutes; however, this variation remains within the 74ALS logic family standard and does not affect functional compatibility in standard logic circuit applications.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS32D and SN74ALS32DR be used interchangeably with DM74ALS1032AMX?

A: Yes. Both parts meet all electrical and mechanical substitution criteria: identical logic function, supply voltage range, input logic levels, operating temperature, and 14-SOIC package configuration. The primary difference is product status and packaging format.

Q: What is the difference between SN74ALS32D and SN74ALS32DR?

A: Both parts are electrically identical. SN74ALS32D is supplied in Tube packaging and carries Last Time Buy status. SN74ALS32DR is supplied in Tape & Reel packaging and maintains Active product status. For new production, SN74ALS32DR is recommended due to ongoing availability.

Q: Are there differences in output current between the original and substitute parts?

A: Yes. The DM74ALS1032AMX specifies output current of 2.6mA (high) and 24mA (low), while both Texas Instruments substitutes specify 400µA (high) and 8mA (low). These differences remain within 74ALS logic family specifications and do not affect functional compatibility in standard logic applications.

Q: What is the propagation delay difference?

A: The DM74ALS1032AMX specifies 12ns maximum propagation delay at 5V with 50pF load. Both SN74ALS32 variants specify 14ns under identical conditions. This 2ns difference is within acceptable timing margins for most logic circuit applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SN74ALS32D and SN74ALS32DR are ROHS3 compliant. The original DM74ALS1032AMX RoHS status is not specified in the provided data.

Q: Can these parts be used in existing PCB designs without modification?

A: Yes. All parts use identical 14-SOIC surface mount packaging with the same pinout and footprint. Direct PCB substitution is possible without design changes.
