Substitute Part Grouping Explanation

Substitute parts for the CY74FCT16374CTPVC are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Series Equivalents (74FCT Series) These parts maintain identical electrical specifications, voltage supply range (4.5V ~ 5.5V), output drive capability (32mA/64mA), and quiescent current (500 µA). They share the same 48-BSSOP package footprint and are pin-compatible. Substitution within this category is based on matching supply voltage, output current ratings, and package geometry.

• 74FCT16374CTPVG (IDT)
• 74FCT16374ATPVG (Renesas Electronics)
• 74FCT16374ATPVG8 (Renesas Electronics)

Category 2: Functional Equivalent with Different Electrical Characteristics (74LVC Series) The SN74LVC16374ADLR operates at a lower voltage supply range (1.65V ~ 3.6V) and exhibits reduced quiescent current (20 µA). While functionally equivalent in logic operation and package footprint, this part requires voltage level translation or operates in lower-power applications. Substitution is valid only when the lower supply voltage and reduced output current (24mA/24mA) are compatible with the target application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Characteristics): Select 74FCT16374CTPVG, 74FCT16374ATPVG, or 74FCT16374ATPVG8 when the application requires identical voltage supply (4.5V ~ 5.5V), output current capability (32mA/64mA), and quiescent current (500 µA) specifications. All three parts are active products with ROHS3 compliance. The 74FCT16374ATPVG and 74FCT16374ATPVG8 have MSL rating of 3 (168 hours), requiring controlled storage conditions, while 74FCT16374CTPVG specifications are not fully detailed. The CY74FCT16374CTPVC has MSL rating of 1 (unlimited), offering superior moisture tolerance.

For Lower-Power Applications: Select SN74LVC16374ADLR only when the application operates at reduced supply voltage (1.65V ~ 3.6V) and can tolerate lower output current (24mA/24mA) and reduced quiescent current (20 µA). This part is manufactured by Texas Instruments with ROHS3 compliance and MSL rating of 1 (unlimited). Voltage level translation may be required if interfacing with 5V logic systems.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original CY74FCT16374CTPVC. Moisture sensitivity levels vary; applications requiring unlimited moisture tolerance should prioritize parts with MSL rating of 1.

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT16374ATPVG as a direct replacement for CY74FCT16374CTPVC? A: Yes. Both parts share identical electrical specifications (4.5V ~ 5.5V supply, 32mA/64mA output current, 500 µA quiescent current), the same 48-BSSOP package footprint, and equivalent logic function. The 74FCT16374ATPVG is an active product, addressing the obsolescence of the original part. Note that the 74FCT16374ATPVG has MSL rating of 3 (168 hours), requiring controlled moisture storage compared to the original part's MSL rating of 1.

Q: What is the difference between 74FCT16374ATPVG and 74FCT16374ATPVG8? A: Both parts are manufactured by Renesas Electronics with identical electrical specifications and package type. The primary difference is packaging format: 74FCT16374ATPVG is supplied in Tube packaging, while 74FCT16374ATPVG8 is supplied in Tape & Reel (TR) format. Electrical performance and pin compatibility are equivalent.

Q: Can I substitute SN74LVC16374ADLR for CY74FCT16374CTPVC in a 5V system? A: No, not without additional circuitry. The SN74LVC16374ADLR operates at 1.65V ~ 3.6V supply voltage, incompatible with 5V systems. Additionally, output current is reduced to 24mA/24mA compared to the original 32mA/64mA. Substitution is valid only in applications designed for lower voltage operation or where voltage level translation is implemented.

Q: Are all substitute parts pin-compatible with the original CY74FCT16374CTPVC? A: Yes. All substitute parts in the 74FCT series (74FCT16374CTPVG, 74FCT16374ATPVG, 74FCT16374ATPVG8) share the same 48-BSSOP package footprint and pin configuration. The SN74LVC16374ADLR also uses the 48-BSSOP package with identical pin assignment, but operates at different voltage levels.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating difference? A: MSL rating indicates maximum exposure time to moisture before component degradation. The original CY74FCT16374CTPVC has MSL 1 (unlimited exposure), while 74FCT16374ATPVG and 74FCT16374ATPVG8 have MSL 3 (168 hours maximum). In high-humidity environments or applications with extended storage, MSL 1 rated parts offer superior reliability without requiring desiccant packaging or controlled storage conditions.

Q: Which substitute part offers the best availability? A: SN74LVC16374ADLR has the highest inventory (41,597 pcs), followed by 74FCT16374ATPVG (1,700 pcs) and 74FCT16374ATPVG8 (1,097 pcs). Availability should be evaluated against electrical compatibility with your specific application requirements.
