Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT162374ATPVC are selected based on functional and electrical compatibility within the following criteria:

Functional Compatibility:

• D-Type flip-flop configuration with 2 elements and 8 bits per element
• Positive edge trigger mechanism
• Tri-state, non-inverted output configuration

Electrical Compatibility:

• Package type: 48-BSSOP surface mount (0.295", 7.50mm Width)
• Operating temperature range: -40°C ~ 85°C (TA)
• RoHS3 compliance and REACH unaffected status

Substitution Groups:

Group 1: 74FCT Series (5V Logic, Same Supply Voltage)

• 74FCT16374ATPVG (Renesas Electronics Corporation)
• 74FCT16374ATPVG8 (Renesas Electronics Corporation)
• 74FCT16374CTPVG (IDT, Integrated Device Technology Inc)

These parts maintain the 74FCT series designation and operate within the 4.5V ~ 5.5V supply voltage range, ensuring direct functional replacement in 5V logic systems.

Group 2: 74ALVCH Series (3.3V Logic, Lower Voltage Operation)

• SN74ALVCH162374DLR (Texas Instruments)

This part operates at 1.65V ~ 3.6V supply voltage and represents a lower-voltage alternative suitable for modern 3.3V logic systems. Substitution requires voltage level compatibility verification in the target application.

Parameter Comparison

Engineering Selection Recommendations

For 5V Logic Systems (Direct Replacement):

The 74FCT16374ATPVG, 74FCT16374ATPVG8, and 74FCT16374CTPVG are active product alternatives within the 74FCT series. All three maintain the 4.5V ~ 5.5V supply voltage specification and identical functional configuration. Selection among these three should be based on packaging format availability (Tube, Tape & Reel, or Bulk) and inventory status. The 74FCT16374CTPVG offers the lowest propagation delay (5.2ns @ 5V, 50pF) among the 74FCT alternatives.

For 3.3V Logic Systems (Voltage-Dependent Substitution):

The SN74ALVCH162374DLR operates at 1.65V ~ 3.6V and is suitable only for applications where the system voltage is compatible with 3.3V logic levels. This part offers reduced quiescent current (40 µA versus 500 µA) and lower output current specifications. Substitution requires confirmation that the target application supports 3.3V operation and that signal level translation is not required.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original CY74FCT162374ATPVC. The 74FCT16374ATPVG and 74FCT16374ATPVG8 have MSL rating of 3 (168 Hours), compared to the original part's MSL rating of 1 (Unlimited). This difference may impact moisture-sensitive handling procedures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162374DLR be used as a direct replacement in a 5V system?

A: No. The SN74ALVCH162374DLR operates at 1.65V ~ 3.6V supply voltage, while the CY74FCT162374ATPVC requires 4.5V ~ 5.5V. Direct substitution in a 5V system would result in component damage or malfunction. Use only if the target application operates at 3.3V logic levels.

Q: What is the difference between the 74FCT16374ATPVG and 74FCT16374ATPVG8?

A: Both parts are functionally identical with the same electrical specifications. The primary difference is packaging format: 74FCT16374ATPVG is supplied in Tube packaging, while 74FCT16374ATPVG8 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and inventory management preferences.

Q: Are all substitute parts available in the same 48-BSSOP package?

A: Yes. All substitute parts listed are housed in the 48-BSSOP (0.295", 7.50mm Width) surface mount package, ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What is the significance of the MSL rating difference?

A: The original CY74FCT162374ATPVC has MSL 1 (Unlimited), while the 74FCT16374ATPVG and 74FCT16374ATPVG8 have MSL 3 (168 Hours). MSL 3 indicates the component must be used within 168 hours of package opening. This requires stricter moisture control during storage and assembly compared to MSL 1 components.

Q: Which substitute part offers the best propagation delay performance?

A: The 74FCT16374CTPVG provides the lowest maximum propagation delay at 5.2ns @ 5V, 50pF, compared to 6.5ns for the other 74FCT alternatives. The SN74ALVCH162374DLR offers 4.6ns @ 3.3V, 50pF but operates at a different supply voltage.

Q: Are all substitute parts RoHS3 compliant?

A: The 74FCT16374ATPVG, 74FCT16374ATPVG8, and SN74ALVCH162374DLR are confirmed ROHS3 compliant. The 74FCT16374CTPVG RoHS status is not specified in the provided data. Verification with the manufacturer is recommended before final selection.
