Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F174ADRE4 is based on strict electrical and mechanical parameter matching within the 74F logic series. The following parameters determine substitution eligibility:

• Functional equivalence: D-type flip-flop with 1 element, 6 bits per element, master reset function
• Electrical specifications: 140 MHz clock frequency, 10 ns maximum propagation delay at 5V/50pF, positive edge trigger, non-inverted outputs
• Power supply compatibility: 4.5V ~ 5.5V operating range
• Output characteristics: 1 mA high current, 20 mA low current
• Package compatibility: 16-SOIC (0.154", 3.90mm Width) surface mount package
• Compliance standards: ROHS3 compliant, MSL Level 1

The SN74F174ADR is identified as the manufacturer-recommended substitute, differing only in packaging format (Tape & Reel vs. individual packaging) while maintaining identical electrical and functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The SN74F174ADR is the direct substitute for the SN74F174ADRE4. Both parts are manufactured by Texas Instruments and share identical electrical, functional, and mechanical specifications. The primary distinction is product status: the SN74F174ADRE4 is discontinued, while the SN74F174ADR remains active with higher inventory availability (4281 Pcs vs. 866 Pcs).

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards. The SN74F174ADR is supplied in Tape & Reel packaging format, which is standard for production environments. Selection of the SN74F174ADR eliminates obsolescence risk and provides improved supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SN74F174ADR directly replace the SN74F174ADRE4 in existing designs?

A: Yes. Both parts are electrically and functionally identical, with matching specifications across all critical parameters including clock frequency, propagation delay, output characteristics, and supply voltage range. The only difference is packaging format and product status.

Q: What is the difference between SN74F174ADRE4 and SN74F174ADR packaging?

A: The SN74F174ADRE4 uses individual packaging, while the SN74F174ADR is supplied in Tape & Reel (TR) format. Both use the same 16-SOIC (0.154", 3.90mm Width) surface mount package. Tape & Reel format is standard for automated assembly and high-volume production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL Level 1 rating, and meet identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Q: Why is the SN74F174ADRE4 discontinued?

A: The SN74F174ADRE4 is discontinued at DiGi Electronics. The SN74F174ADR remains the active product offering from Texas Instruments for this logic function.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: D-type flip-flop configuration (1 element, 6 bits), 140 MHz clock frequency, 10 ns propagation delay at 5V/50pF, positive edge triggering, non-inverted outputs, 4.5V ~ 5.5V supply range, and 16-SOIC package format.
