Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT162374TPVC are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Type: D-Type flip-flop architecture
• Number of Elements: 2
• Number of Bits per Element: 8
• Output Type: Tri-State, Non-Inverted
• Trigger Type: Positive Edge
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Compatibility Criteria:

• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 48-SSOP

All substitute parts listed maintain these core parameters, ensuring pin-compatible and functionally equivalent operation. Variations in propagation delay, output current ratings, input capacitance, and packaging format (Tube, Tape & Reel, Bulk) do not affect core substitutability but may influence performance characteristics and procurement logistics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs): The 74FCT16374CTPVG manufactured by IDT is the preferred substitute. This part is in active production status, offers improved propagation delay performance (5.2ns versus 6.5ns), and maintains full electrical and mechanical compatibility with the obsolete CY74FCT162374TPVC. The part is ROHS3 compliant and suitable for applications requiring enhanced speed performance within the same package footprint.

Alternative Substitutes (Active Production): The 74FCT16374ATPVG and 74FCT16374ATPVG8 manufactured by Renesas Electronics are functionally equivalent alternatives. Both parts are in active production status and ROHS3 compliant. The primary difference between these two is packaging format: 74FCT16374ATPVG is supplied in Tube packaging, while 74FCT16374ATPVG8 is supplied in Tape & Reel format. Selection between these variants depends on procurement and assembly requirements.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original part. The obsolete status of the CY74FCT162374TPVC necessitates transition to one of the active production substitutes for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT16374ATPVG directly replace the CY74FCT162374TPVC in existing designs? A: Yes. The 74FCT16374ATPVG is pin-compatible and functionally equivalent. Both parts share identical package geometry (48-BSSOP), electrical specifications for supply voltage, operating temperature range, and output configuration. No circuit modifications are required.

Q: What is the difference between 74FCT16374ATPVG and 74FCT16374ATPVG8? A: These parts are electrically identical. The difference is packaging format: 74FCT16374ATPVG is supplied in Tube packaging, while 74FCT16374ATPVG8 is supplied in Tape & Reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Why does the 74FCT16374CTPVG have faster propagation delay than the Renesas alternatives? A: The 74FCT16374CTPVG (IDT) specifies 5.2ns propagation delay compared to 6.5ns for the Renesas parts. This represents improved speed performance within the same functional class. Both specifications meet the 74FCT logic family performance envelope and are suitable for equivalent applications.

Q: Are there output current differences between the main part and substitutes? A: Yes. The CY74FCT162374TPVC specifies 24mA output current (both high and low). The substitute parts specify 32mA high and 64mA low output current. These higher ratings provide additional drive capability and are backward compatible with designs expecting the lower original specifications.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference? A: The CY74FCT162374TPVC has MSL 1 (unlimited shelf life). The Renesas substitutes have MSL 3 (168 hours). This affects storage and handling procedures. MSL 3 components require controlled humidity storage and have a 168-hour floor life after moisture exposure. Standard industrial handling practices accommodate this requirement.

Q: Are all substitute parts ROHS3 compliant? A: The 74FCT16374ATPVG and 74FCT16374ATPVG8 (Renesas) are explicitly ROHS3 compliant. The 74FCT16374CTPVG (IDT) compliance status is not specified in the provided data. Verify ROHS3 compliance with IDT if this certification is required for your application.

Q: Can I use these parts interchangeably in the same assembly? A: Yes, within the constraints of packaging format. All three substitute parts are pin-compatible and functionally equivalent. If your assembly process uses automated tape-and-reel feeding, select 74FCT16374ATPVG8. If manual or tube-based assembly is used, select 74FCT16374ATPVG or 74FCT16374CTPVG based on availability.
