Engineering Selection Recommendations

For New Designs: SN7406N or SN7416N are the preferred selections. Both Texas Instruments parts are in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment for modern applications.

For Legacy System Maintenance: Either SN7406N or SN7416N provides direct functional replacement for DM7406N installations. The identical electrical parameters and 14-DIP package configuration ensure pin-for-pin compatibility without circuit modification.

Compliance Considerations: The DM7406N is RoHS non-compliant. Both substitute parts (SN7406N and SN7416N) are ROHS3 compliant, meeting current environmental and regulatory requirements for component procurement and assembly.

Inventory and Availability: Both Texas Instruments substitutes maintain active production status with documented stock availability, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can SN7406N and SN7416N be used interchangeably with DM7406N?

A: Yes. Both parts meet all specified electrical parameters (supply voltage, output current, logic levels, propagation delay) and share identical 14-DIP package configuration. Pin-for-pin substitution is supported without circuit redesign.

Q: What is the difference between SN7406N and SN7416N?

A: Both parts are parametric equivalents with identical electrical specifications and package configuration as listed in the parameter comparison table. Selection between them depends on supplier availability and procurement requirements.

Q: Are there package alternatives available?

A: The substitute parts specified (SN7406N and SN7416N) are available in 14-PDIP package configuration, which is mechanically and electrically compatible with the 14-DIP (0.300", 7.62mm) package of the DM7406N for through-hole mounting applications.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both ROHS3-compliant substitutes deliver identical functional characteristics within the specified operating parameters.

Q: What supply voltage range applies to all three parts?

A: All three parts (DM7406N, SN7406N, SN7416N) operate within the 4.75V ~ 5.25V supply voltage range with identical input and output specifications.
