CD74HCT153M Equivalent & Substitute Parts

Part Overview

The CD74HCT153M is a 2 x 4:1 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited availability from the original manufacturer. The part operates with a single 4.5V to 5.5V supply and delivers 4mA output current at both high and low logic levels. Finding equivalent and substitute parts is necessary due to the Last Time Buy status and to ensure design flexibility across manufacturing batches and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HCT153M is determined by the following critical parameters:

• Circuit Configuration: Must be 2 x 4:1 multiplexer topology
• Package Type: Must be 16-SOIC surface mount with 0.154" (3.90mm) width
• Electrical Specifications: Voltage supply 4.5V ~ 5.5V, output current 4mA/4mA
• Operating Temperature Range: Minimum -40°C to -55°C lower bound; maximum 125°C
• Compliance: RoHS3 compliance preferred for new designs

Substitute parts are grouped into two categories: manufacturer-recommended direct substitutes with identical or superior specifications, and parametric equivalents that meet all functional requirements within the allowed parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT153M96 (Texas Instruments) is the primary recommended substitute. This part is manufactured by the same supplier as the main part, maintains identical electrical and thermal specifications, and carries Active product status with ROHS3 compliance. The only difference is packaging format (Tape & Reel versus Tube), which is a procurement consideration rather than a functional limitation.

74HCT153D,653 (Nexperia USA Inc.) is a secondary recommended substitute. This part is Active, ROHS3 compliant, and meets all functional requirements. The operating temperature range is -40°C to 125°C, which is narrower at the lower bound by 15°C compared to the main part. This part is suitable for applications where the lower temperature limit of -40°C is acceptable.

CD74HCT253M (Harris Corporation) meets all parametric requirements but carries Obsolete product status and is RoHS non-compliant. This part should be avoided for new designs and is listed only for reference in legacy system maintenance scenarios.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT153M96 be used as a direct replacement for CD74HCT153M?

A: Yes. CD74HCT153M96 is electrically and functionally identical to CD74HCT153M. The difference is packaging format: CD74HCT153M96 is supplied in Tape & Reel format while CD74HCT153M is supplied in Tube format. Both are suitable for PCB assembly processes.

Q: What is the difference between the 16-SOIC and 16-SO package designations?

A: Both designations refer to the same 16-pin Small Outline Integrated Circuit package with 0.154" (3.90mm) width. The designations are manufacturer-specific nomenclature variations and do not indicate functional or dimensional differences.

Q: Is 74HCT153D,653 suitable for applications requiring -55°C operation?

A: No. The 74HCT153D,653 has a minimum operating temperature of -40°C. If your application requires operation at -55°C, use CD74HCT153M or CD74HCT153M96, both of which support the full -55°C to 125°C range.

Q: Why is CD74HCT253M listed if it is obsolete?

A: CD74HCT253M is included for reference purposes only, particularly for engineers maintaining or repairing legacy systems that may contain this part. For new designs, CD74HCT253M should not be selected due to its Obsolete status and RoHS non-compliance.

Q: Are all substitute parts ROHS3 compliant?

A: No. CD74HCT253M is RoHS non-compliant. CD74HCT153M96 and 74HCT153D,653 are both ROHS3 compliant and are the recommended choices for applications subject to RoHS regulations.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes, within the specified operating range. All recommended substitutes (CD74HCT153M96 and 74HCT153D,653) support operation up to 125°C. Verify that your specific application does not exceed this maximum temperature.
