Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DM74AS1032AMX are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Logic Type: OR Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Voltage - Supply: 4.5V ~ 5.5V
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Performance Parameters (Allowable Variation):

• Current - Output High, Low: Variation permitted within logic specifications
• Max Propagation Delay @ V, Max CL: Variation permitted within logic specifications

The substitute parts listed below meet all core electrical and mechanical requirements and are therefore functionally interchangeable with the DM74AS1032AMX in applications where these parameters are specified.

Parameter Comparison

Engineering Selection Recommendations

SN74AS1032AD (Texas Instruments) is the primary direct substitute for the DM74AS1032AMX. This part maintains identical electrical and performance characteristics, including output current ratings and propagation delay specifications. The SN74AS1032AD carries Active product status and ROHS3 compliance, making it suitable for new designs and long-term production applications.

SN74AS32D (Texas Instruments) and SN74AS32DR (Texas Instruments) are functionally equivalent alternatives with the same logic configuration and package. These parts exhibit reduced output current specifications (2mA, 20mA versus 48mA, 48mA) and slightly improved propagation delay (5.8ns versus 6.3ns). The SN74AS32D is designated Last Time Buy, while the SN74AS32DR maintains Active status. Both are ROHS3 compliant. Selection between these variants should be based on application current requirements and packaging preference (Tube versus Tape & Reel).

For applications requiring the highest availability and longest product lifecycle support, SN74AS32DR is recommended due to its Active status and Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can SN74AS1032AD be used as a direct replacement for DM74AS1032AMX?

A: Yes. The SN74AS1032AD meets all core electrical parameters, input/output logic levels, supply voltage range, operating temperature range, and package specifications of the DM74AS1032AMX. Both parts are 4-channel 2-input OR gates in 14-SOIC surface mount packaging.

Q: What is the difference between SN74AS1032AD and SN74AS32D?

A: Both are 4-channel 2-input OR gates in 14-SOIC packaging with identical logic specifications. The primary differences are output current ratings (SN74AS1032AD: 48mA/48mA; SN74AS32D: 2mA/20mA) and propagation delay (SN74AS1032AD: 6.3ns; SN74AS32D: 5.8ns). Selection depends on application current requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (SN74AS1032AD, SN74AS32D, SN74AS32DR) are ROHS3 compliant. The original DM74AS1032AMX RoHS status is not specified in the provided data.

Q: What packaging options are available for these substitutes?

A: SN74AS1032AD is supplied in Tube packaging. SN74AS32D is supplied in Tube packaging. SN74AS32DR is supplied in Tape & Reel (TR) format. All three maintain the same 14-SOIC physical package.

Q: Is SN74AS32D still in production?

A: SN74AS32D is designated Last Time Buy, indicating limited future availability. For new designs requiring long-term supply assurance, SN74AS1032AD or SN74AS32DR (both Active status) are preferred.

Q: Do all substitute parts operate at the same supply voltage?

A: Yes. All substitute parts operate within the 4.5V to 5.5V supply voltage range, matching the DM74AS1032AMX specification.
