Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT16373CTPACT are identified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Equivalence Criteria:

• Logic type: D-Type Transparent Latch
• Circuit configuration: 8:8
• Independent circuits: 2
• Output type: Tri-State
• Package type: 48-TFSOP (0.240", 6.10mm Width)
• Operating temperature range: -40°C ~ 85°C

Electrical Compatibility Considerations:

• Voltage supply range compatibility
• Propagation delay time specifications
• Output current drive capabilities

Two substitute parts are identified:

1. SN74LVC16373ADGGR (MFR Recommended): Active product status with identical functional and mechanical specifications. Operates at lower voltage range (1.65V ~ 3.6V) with comparable propagation delay (2.1ns) and reduced output current drive (24mA / 24mA).

2. CY74FCT16373ATPACT (Parametric Equivalent): Obsolete product with identical electrical and mechanical specifications to the main part, differing only in packaging designation (tape reel variant).

Parameter Comparison

Engineering Selection Recommendations

SN74LVC16373ADGGR is the primary substitute for new designs and procurement. This part maintains active product status with full manufacturer support, ensuring long-term availability and supply chain stability. All functional and mechanical parameters align with the CY74FCT16373CTPACT, with the exception of voltage supply range. The SN74LVC16373ADGGR operates at 1.65V ~ 3.6V, making it suitable for low-voltage applications. Propagation delay (2.1ns) and output current specifications remain within acceptable operational parameters for equivalent circuit performance.

CY74FCT16373ATPACT serves as a parametric equivalent for applications requiring identical electrical specifications (4.5V ~ 5.5V supply, 2ns propagation delay, 32mA / 64mA output current). However, this part shares obsolete status with the main component, limiting its utility for new procurement strategies.

Both substitute parts are ROHS3 compliant with MSL 1 rating, maintaining environmental and reliability standards equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC16373ADGGR replace CY74FCT16373CTPACT in existing designs?

A: Functional and mechanical compatibility is confirmed. The primary consideration is voltage supply range: SN74LVC16373ADGGR operates at 1.65V ~ 3.6V versus the original 4.5V ~ 5.5V. Designs operating within the lower voltage range can implement this substitute directly. Designs requiring 5V operation require voltage level translation or alternative supply architecture.

Q: What is the difference between CY74FCT16373CTPACT and CY74FCT16373ATPACT?

A: Both parts are parametrically identical in electrical and functional specifications. The difference lies in packaging designation: CTPACT indicates Cut Tape packaging, while ATPACT indicates tape reel packaging. Both are 48-TSSOP packages with identical pin configurations and performance characteristics.

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

A: Yes. All three parts (CY74FCT16373CTPACT, SN74LVC16373ADGGR, and CY74FCT16373ATPACT) are supplied in 48-TFSOP (0.240", 6.10mm Width) surface mount packages with identical pinouts, enabling direct board-level substitution without layout modifications.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage or handling.

Q: How do propagation delay specifications compare?

A: CY74FCT16373CTPACT and CY74FCT16373ATPACT both specify 2ns propagation delay. SN74LVC16373ADGGR specifies 2.1ns, representing a 0.1ns increase. This difference is negligible for most digital logic applications and does not impact functional compatibility.
