Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74FCT541M96 is determined by the following critical parameters:

• Logic Function: Buffer, Non-Inverting with 1 Element and 8 Bits per Element
• Output Configuration: 3-State output capability
• Supply Voltage Range: 4.75V ~ 5.25V compatibility
• Package Type: 20-SOIC surface mount package with identical physical dimensions
• Base Product Series: 74FCT logic family

The substitute part CY74FCT541CTSOCT maintains functional equivalence across all core logic parameters and package specifications. The primary difference is product status (active vs. obsolete) and extended operating temperature range, which represents an enhancement rather than a limitation for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The CY74FCT541CTSOCT is the active equivalent for the obsolete CD74FCT541M96. Both parts are manufactured by Texas Instruments and maintain identical logic functionality, supply voltage specifications, and physical package dimensions. The substitute part is ROHS3 compliant and carries active product status, ensuring long-term availability and supply chain continuity.

The CY74FCT541CTSOCT provides enhanced output current capability on the high side (32mA vs. 15mA) and an extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C), representing functional improvements suitable for direct substitution in applications originally designed for the CD74FCT541M96.

Frequently Asked Questions (FAQ)

Q: Can the CY74FCT541CTSOCT directly replace the CD74FCT541M96 in existing designs?

A: Yes. Both parts share identical logic function, supply voltage range, and 20-SOIC package dimensions. The substitute part is pin-compatible and functionally equivalent.

Q: What is the significance of the different output current ratings?

A: The CY74FCT541CTSOCT provides higher output current capability on the high side (32mA vs. 15mA). This represents an enhancement and does not restrict substitution. Applications requiring the original 15mA specification will operate within the substitute part's capabilities.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: No. The extended operating temperature range (-40°C ~ 85°C) of the CY74FCT541CTSOCT encompasses the original part's range (0°C ~ 70°C). This represents an enhancement for applications requiring broader temperature operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD74FCT541M96 and CY74FCT541CTSOCT are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: Why is the CD74FCT541M96 classified as obsolete?

A: Product obsolescence reflects Texas Instruments' lifecycle management. The CY74FCT541CTSOCT is the active equivalent and recommended for new designs and production applications.
