Substitute Part Grouping Explanation

Substitute parts for the CY74FCT16373CTPVC are identified based on strict alignment with the following critical parameters:

Functional Equivalence Criteria:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Independent Circuits: 2
• Output Type: Tri-State
• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Electrical Compatibility Criteria:

• Operating Temperature Range: -40°C ~ 85°C
• Propagation Delay: 2ns or better
• Output Current Capability: Minimum 32mA (High), 64mA (Low)

Compliance Criteria:

• RoHS3 Compliant
• MSL Rating: 1 (Unlimited)

Two substitute parts meet these criteria:

1. SN74LVC16373ADLR (MFR Recommended) - Active product status with identical functional and package specifications. Operates at lower supply voltage (1.65V ~ 3.6V) with equivalent propagation delay and reduced output current.

2. CY74FCT16373ATPVC (Parametric Equivalent) - Identical electrical and functional specifications to the main part with matching 74FCT series characteristics. Differs only in packaging format (Tube vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

SN74LVC16373ADLR is the primary substitute for new designs and ongoing production. This part maintains full functional and package compatibility while offering active product status from Texas Instruments. The lower supply voltage range (1.65V ~ 3.6V) provides flexibility for modern low-power applications, though designs operating at 5V must verify compatibility with the reduced output current specifications (24mA vs. 32mA for high output). All compliance certifications (ROHS3, MSL 1) are maintained.

CY74FCT16373ATPVC serves as a parametric equivalent for applications requiring exact electrical specifications matching the original CY74FCT16373CTPVC. This part is suitable for direct replacement in existing designs where 74FCT series performance characteristics are specified. However, obsolete product status limits its availability for long-term production support.

For new system designs, SN74LVC16373ADLR is the recommended selection due to active product status and manufacturer support continuity.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC16373ADLR replace CY74FCT16373CTPVC in a 5V system?

A: SN74LVC16373ADLR operates within 1.65V to 3.6V supply range, which does not include 5V operation. Direct substitution in 5V systems requires circuit redesign or voltage regulation. The part is suitable for 3.3V and lower voltage applications.

Q: What is the difference between CY74FCT16373CTPVC and CY74FCT16373ATPVC?

A: Both parts are electrically and functionally identical with matching 74FCT series specifications. The primary difference is packaging format: CY74FCT16373CTPVC is supplied in Tape & Reel format, while CY74FCT16373ATPVC is supplied in Tube format. Selection depends on procurement and assembly requirements.

Q: Are all substitute parts pin-compatible?

A: Yes. All listed substitute parts use the 48-BSSOP package with identical pinout and functional assignment. PCB layout modifications are not required for substitution.

Q: Do substitute parts maintain RoHS3 compliance?

A: Yes. Both SN74LVC16373ADLR and CY74FCT16373ATPVC are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's compliance status.

Q: What is the propagation delay difference between SN74LVC16373ADLR and the original part?

A: SN74LVC16373ADLR has 2.1ns propagation delay compared to 2ns for CY74FCT16373CTPVC. This 0.1ns difference is within typical application tolerances for latch timing specifications.

Q: Why is CY74FCT16373CTPVC marked as obsolete?

A: The 74FCT series represents older CMOS logic technology. Texas Instruments has transitioned to the 74LVC series for new production, offering improved power efficiency and broader voltage compatibility while maintaining functional equivalence.
