Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74AS1004AN is determined by strict equivalence across the following parameters:

• Logic family and type (74AS Inverter)
• Number of circuits (6) and inputs (1)
• Electrical specifications: supply voltage range (4.5V ~ 5.5V), output current (48mA), input logic levels (0.8V low, 2V high), and propagation delay (4ns @ 5V, 50pF)
• Operating temperature range (0°C ~ 70°C)
• Physical package compatibility (14-DIP form factor, 0.300" spacing)

The SN74AS1004AN from Texas Instruments meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance and mechanical compatibility, differing only in manufacturer and product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS1004AN is the direct substitute for the DM74AS1004AN. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the DM74AS1004AN is obsolete, while the SN74AS1004AN maintains active status with current manufacturing support.

The SN74AS1004AN offers additional compliance advantage through ROHS3 certification, whereas the DM74AS1004AN is classified as REACH Unaffected. Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. For new designs or system refreshes, the SN74AS1004AN is the appropriate selection due to its active product status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS1004AN directly replace the DM74AS1004AN in existing designs?

A: Yes. The SN74AS1004AN is a parametric equivalent with identical electrical specifications, output current ratings, propagation delay, and 14-DIP package dimensions. No circuit modifications are required.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 14-DIP (0.300", 7.62mm) through-hole package. Pin-to-pin compatibility is complete.

Q: Why is the DM74AS1004AN listed as obsolete?

A: Obsolescence reflects onsemi's discontinuation of this part number. The SN74AS1004AN from Texas Instruments remains in active production and is the recommended long-term source.

Q: Do the parts differ in supply voltage or operating temperature requirements?

A: No. Both parts operate identically across the 4.5V to 5.5V supply range and 0°C to 70°C temperature range.

Q: What is the significance of the RoHS3 compliance on the SN74AS1004AN?

A: ROHS3 compliance indicates adherence to current environmental and hazardous substance restrictions. This is relevant for applications subject to regulatory compliance requirements. The DM74AS1004AN's REACH Unaffected status indicates it does not fall under REACH substance restrictions.
