SN74HC253D Equivalent & Substitute Parts

Part Overview

The SN74HC253D is a 2 x 4:1 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement. The SN74HC253D operates across a 2V to 6V supply range with output currents of 7.8mA (both high and low), suitable for general-purpose logic multiplexing applications requiring dual independent 4:1 selection circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74HC253D is determined by strict equivalence across the following critical parameters: circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC surface mount), voltage supply range (2V ~ 6V), output current specifications (7.8mA), and RoHS3 compliance. Parts are grouped into three categories based on substitution relationship type:

Direct Manufacturer Equivalent: Parts with identical electrical specifications and packaging from the original manufacturer or authorized equivalents, differing only in packaging format (Tape & Reel vs. Tube).

Manufacturer Recommended Equivalent: Parts from alternative manufacturers (Nexperia USA Inc.) that maintain all core electrical parameters and package dimensions, with extended operating temperature ranges or automotive-grade qualifications.

Parametric Equivalent: Parts with matching circuit configuration and electrical specifications but potentially different base product numbering, requiring functional verification for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: SN74HC253DR is the primary direct substitute. It maintains identical electrical specifications and 16-SOIC packaging as the original SN74HC253D while offering active product status and higher inventory availability. The only difference is packaging format (Tape & Reel vs. Tube), which does not affect electrical performance.

For Extended Temperature Range Requirements: 74HC253D,653 (Nexperia) and 74HC253D-Q100,118 (Nexperia, automotive-grade) both extend the operating temperature range to -40°C ~ 125°C. These are suitable for applications requiring higher thermal performance while maintaining all other electrical parameters and RoHS3 compliance.

For Automotive Applications: 74HC253D-Q100,118 is the appropriate selection, offering AEC-Q100 automotive qualification alongside the extended temperature range. This part is specifically qualified for automotive-grade reliability and environmental stress screening.

For Parametric Equivalence: SN74HC153D shares identical electrical specifications and package dimensions but uses a different base product number. This part is discontinued and should only be considered if existing design documentation specifically references this part number.

Frequently Asked Questions (FAQ)

Q: Can SN74HC253DR be used as a direct replacement for SN74HC253D? A: Yes. SN74HC253DR is a direct electrical and functional equivalent. Both parts share identical circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), voltage supply range (2V ~ 6V), output current specifications (7.8mA), and operating temperature range (-40°C ~ 85°C). The only difference is packaging format (Tape & Reel vs. Tube), which does not affect circuit performance.

Q: What is the difference between the Nexperia parts (74HC253D,653 and 74HC253D-Q100,118) and the Texas Instruments parts? A: The Nexperia parts maintain all core electrical specifications but extend the operating temperature range to -40°C ~ 125°C. The 74HC253D-Q100,118 variant adds AEC-Q100 automotive qualification. Both are ROHS3 compliant and suitable for applications requiring higher thermal performance or automotive-grade reliability.

Q: Is SN74HC153D a suitable substitute for SN74HC253D? A: SN74HC153D is a parametric equivalent with matching electrical specifications and package dimensions. However, it uses a different base product number and is currently discontinued. It should only be used if existing design documentation specifically requires this part number or if no other alternatives are available.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (SN74HC253DR, 74HC253D,653, 74HC253D-Q100,118, and SN74HC153D) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original SN74HC253D specifications.

Q: Can I use the automotive-grade 74HC253D-Q100,118 in non-automotive applications? A: Yes. The automotive-grade part exceeds standard requirements and is fully compatible with non-automotive applications. It offers extended temperature range (-40°C ~ 125°C) and additional reliability screening, making it suitable for any application requiring enhanced performance specifications.

Q: What packaging formats are available for these substitutes? A: SN74HC253D and SN74HC153D are supplied in Tube packaging. SN74HC253DR, 74HC253D,653, and 74HC253D-Q100,118 are supplied in Tape & Reel (TR) format. Both packaging formats contain identical components; the difference is in handling and storage method for automated assembly processes.
