Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC253D,652 is determined by the following critical parameters:

• Circuit configuration: 2 x 4:1 multiplexer topology
• Package type: 16-SOIC surface mount package
• Voltage supply range: 2V ~ 6V single supply
• Output current capability: 7.8mA high and low
• Electrical compatibility: CMOS logic family (74HC series)

Substitute parts are grouped into two categories based on product status and compliance:

Upgrade Parts (Active or higher compliance status): CD74HC253MT and CD74HC253M provide direct functional replacement with improved availability and compliance profiles.

Similar Parts (Active alternatives): SN74HC253DR, SN74HC253D, SN74HC253DT, SN74HC253QDREP, and SN74HC253QDRG4Q1 offer equivalent electrical performance with variations in packaging format and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74HC253MT

CD74HC253MT is the preferred upgrade substitute. It maintains full electrical equivalence with the 74HC253D,652 across all critical parameters: 2 x 4:1 multiplexer configuration, 16-SOIC package, 2V ~ 6V supply range, and 7.8mA output current. The part is currently active in production, ROHS3 compliant, and available in Tape & Reel packaging for automated assembly. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin compared to the original part.

Secondary Recommendation: SN74HC253DR

SN74HC253DR offers active product status with ROHS3 compliance and Tape & Reel packaging. It provides equivalent electrical performance with the same 16-SOIC package and 2V ~ 6V supply specification. The operating temperature range is -40°C ~ 85°C, which is narrower than the original part but suitable for most commercial applications.

Alternative for Automotive Applications: SN74HC253QDRG4Q1

For automotive-grade applications requiring AEC-Q100 qualification, SN74HC253QDRG4Q1 provides the same 2 x 4:1 multiplexer functionality with automotive-level reliability assurance. This part maintains the full -40°C ~ 125°C operating temperature range and ROHS3 compliance.

Not Recommended: CD74HC253M

CD74HC253M is RoHS non-compliant and obsolete, making it unsuitable for new designs despite functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74HC253D,652 with CD74HC253MT in my design?

A: Yes. Both parts share identical circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), voltage supply range (2V ~ 6V), and output current specifications (7.8mA). Pin-to-pin compatibility is maintained. The primary difference is packaging format (Tube vs. Tape & Reel) and extended temperature range in CD74HC253MT.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and small-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly in high-volume production. Both formats contain identical die and electrical performance.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not affect electrical substitution compatibility. The 74HC253D,652 operates -40°C ~ 125°C, while some alternatives operate -40°C ~ 85°C. If your application requires operation above 85°C, select parts with extended range such as CD74HC253MT (-55°C ~ 125°C) or SN74HC253QDRG4Q1 (-40°C ~ 125°C).

Q: Is RoHS compliance a substitution requirement?

A: RoHS compliance is a regulatory and procurement requirement, not an electrical substitution criterion. For new designs and regulated markets, ROHS3-compliant parts are mandatory. CD74HC253MT and SN74HC253DR both meet ROHS3 requirements. CD74HC253M is RoHS non-compliant and unsuitable for regulated applications.

Q: Can I use SN74HC253D or SN74HC253DT as substitutes?

A: SN74HC253D and SN74HC253DT are electrically equivalent but discontinued at DiGi Electronics. While they maintain the required 2 x 4:1 configuration and 16-SOIC package, active alternatives such as SN74HC253DR or CD74HC253MT are preferred for new procurement due to ongoing availability.

Q: What does AEC-Q100 qualification mean for SN74HC253QDRG4Q1?

A: AEC-Q100 is an automotive industry qualification standard. SN74HC253QDRG4Q1 meets automotive-grade reliability requirements and is suitable for automotive applications. Standard-grade alternatives (CD74HC253MT, SN74HC253DR) are not automotive-qualified and should not be used in automotive designs without additional validation.
