Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the I74F657D,118 is determined by the following critical parameters:

• Logic type and functional configuration (Transceiver, Non-Inverting)
• Element and bit-per-element count (1 element, 8 bits per element)
• Output type (3-State)
• Supply voltage range (4.5V ~ 5.5V)
• Package and physical form factor (24-SOIC, 0.295" width, 7.50mm)
• Surface mount compatibility
• Compliance certifications (RoHS3, REACH Unaffected)

The SN74F657DW from Texas Instruments meets all these substitution criteria. Both components share identical logic architecture, pin configuration, electrical supply requirements, and physical packaging specifications. The substitute maintains full functional and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The SN74F657DW is a direct functional equivalent to the I74F657D,118. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.

The primary distinction between the two parts is product status: the original I74F657D,118 is obsolete, while the SN74F657DW maintains active production status. This status difference ensures ongoing availability and supply chain continuity for the SN74F657DW.

Selection of the SN74F657DW is appropriate for applications requiring the functional and electrical characteristics of the original I74F657D,118 where component availability is a consideration.

Frequently Asked Questions (FAQ)

Q: Can the SN74F657DW be used as a direct replacement for the I74F657D,118?

A: Yes. Both components share identical logic type, element configuration, bit-per-element count, output type, supply voltage range, and 24-SOIC package specifications. Pin-for-pin and functional compatibility is confirmed.

Q: Are there differences in operating temperature ranges between these parts?

A: The I74F657D,118 operates from -40°C to 85°C, while the SN74F657DW operates from 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use the original I74F657D,118 or identify alternative components with extended temperature specifications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the I74F657D,118 and SN74F657DW are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the different product statuses?

A: The I74F657D,118 is obsolete, indicating discontinued manufacturing. The SN74F657DW is active, ensuring ongoing availability and supply chain support. For new designs or long-term production requirements, the active status of the SN74F657DW provides supply continuity advantages.

Q: Are the output current specifications identical?

A: Yes. Both components specify 3mA output high current and 24mA output low current, confirming electrical compatibility in drive capability.
