Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HCT253M96 is determined by the following critical parameters: circuit configuration (2 x 4:1 multiplexer function), voltage supply range (4.5V ~ 5.5V), package type (16-SOIC), and output current capability (4mA minimum). Substitute parts are grouped into two categories based on functional equivalence and product status:

Category 1: Parametric Equivalents (Identical Electrical Specifications) Parts that maintain the same circuit configuration, voltage supply range, output current ratings, and package dimensions. These parts are direct functional replacements with identical pin configurations and electrical performance.

Category 2: Manufacturer Recommended Alternatives (Enhanced or Alternative Specifications) Parts that provide the same multiplexer function but with different voltage supply ranges, output current capabilities, or package variants. These parts require design verification for compatibility with existing circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74HCT153M96 (Texas Instruments) This part is the direct parametric equivalent with identical electrical specifications and package configuration. It maintains active product status, ensuring long-term availability and supply chain stability. This is the preferred replacement for the obsolete CD74HCT253M96.

Secondary Recommendation: 74HCT253D,653 (Nexperia USA Inc.) This part provides the same circuit configuration and voltage supply range with enhanced output current capability (6mA versus 4mA). It is manufactured by Nexperia, an established logic IC supplier, and maintains active product status. The increased output current provides additional design margin for applications requiring higher drive capability.

Tertiary Recommendation: 74HCT253D-Q100,118 (NXP USA Inc.) This automotive-qualified variant (AEC-Q100) is suitable for applications requiring automotive-grade components. It provides identical electrical performance to the Nexperia equivalent with formal automotive qualification documentation.

Alternative for Extended Voltage Range: SN74HCS153PWR (Texas Instruments) This part extends the supply voltage range to 2V ~ 6V and provides higher output current (7.8mA). The 16-TSSOP package is a smaller footprint alternative. This option is suitable for designs requiring lower supply voltages or enhanced output drive capability, with the trade-off of package size change.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT153M96 directly replace CD74HCT253M96 without circuit modification? A: Yes. CD74HCT153M96 is a parametric equivalent with identical voltage supply range (4.5V ~ 5.5V), output current ratings (4mA / 4mA), operating temperature range (-55°C ~ 125°C), and 16-SOIC package configuration. Pin-for-pin compatibility is maintained.

Q: What is the difference between the 74HCT253D,653 and CD74HCT253M96? A: Both parts maintain the same 2 x 4:1 multiplexer circuit configuration and 16-SOIC package. The 74HCT253D,653 provides higher output current (6mA versus 4mA) and operates over a narrower temperature range (-40°C ~ 125°C versus -55°C ~ 125°C). The higher output current provides additional design margin for driving capacitive or resistive loads.

Q: Is the SN74HCS153PWR compatible with existing CD74HCT253M96 designs? A: The SN74HCS153PWR maintains the same 2 x 4:1 multiplexer function and voltage supply compatibility (2V ~ 6V range includes the 4.5V ~ 5.5V operating window). However, the package changes from 16-SOIC to 16-TSSOP, requiring PCB layout modification. Pin assignment must be verified against the respective datasheets.

Q: Why is CD74HCT253M96 marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued production and will not accept new orders. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Migration to active alternatives is recommended for new designs and ongoing production.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original CD74HCT253M96 environmental compliance requirements.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging? A: Cut Tape packaging provides individual components cut from the reel, suitable for small-quantity orders and manual assembly. Tape & Reel packaging maintains components on the continuous reel for automated pick-and-place assembly. Both packaging formats contain identical components; the difference is in delivery and handling format.
