Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT16373ATPVG is determined by strict alignment with the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2 Channel 8:8
• Output Type: Tri-State
• Supply Voltage Range: 4.5V ~ 5.5V
• Package: 48-BSSOP surface mount
• Operating Temperature Range: -40°C ~ 85°C

Substitute parts must maintain identical logic function, channel configuration, and physical package specifications. Variations in propagation delay, output current ratings, and MSL classifications are permissible provided the substitute meets or exceeds the performance envelope of the original part. All identified substitutes share the base product number 74FCT16373 or 74FCT162373 series designation and are compatible with the same PCB footprint and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain functional equivalence with the 74FCT16373ATPVG across the critical parameters of logic type, circuit configuration, output type, supply voltage, and package specification. Selection among substitutes should prioritize product status and compliance certifications:

CY74FCT162373ATPVC (Cypress Semiconductor) is the preferred substitute, offering active product status and unlimited MSL rating, ensuring long-term availability and reduced moisture sensitivity risk during storage and assembly operations.

CY74FCT16373ATPVC and CY74FCT16373ATPVCT (Texas Instruments) provide direct functional equivalence with improved MSL ratings (1 vs. 3) and are suitable for applications where extended shelf life is required. Both maintain the original output current specifications of 32mA/64mA.

CY74FCT162373CTPVC (Texas Instruments) offers equivalent functionality with reduced output current ratings (24mA/24mA) and should be evaluated for applications where lower drive capability is acceptable.

CY74FCT16373CTPVC (Texas Instruments) maintains the original 32mA/64mA output current specification and is compatible with designs requiring higher output drive capability.

All substitutes comply with ROHS3 requirements and operate within the specified temperature range. Propagation delay variations (1.5ns vs. 2ns) are within acceptable tolerances for most applications but should be verified against timing-critical circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can CY74FCT162373ATPVC be used as a direct replacement for 74FCT16373ATPVG?

A: Yes. Both parts share identical logic type (D-Type Transparent Latch), circuit configuration (2 Channel 8:8), output type (Tri-State), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and 48-BSSOP package specification. The CY74FCT162373ATPVC offers the additional advantage of active product status and unlimited MSL rating.

Q: What is the significance of the propagation delay difference between 1.5ns and 2ns?

A: The 74FCT16373ATPVG specifies 1.5ns propagation delay, while most substitutes specify 2ns. This 0.5ns difference is negligible for most standard logic applications. However, designs with timing margins less than 0.5ns should be re-evaluated to confirm compatibility with the substitute part's propagation delay specification.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All identified substitutes use the 48-BSSOP package with identical pin configuration and physical dimensions (0.295", 7.50mm Width). Direct PCB footprint compatibility is confirmed.

Q: What does MSL rating mean, and why does it vary among substitutes?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient moisture before assembly. The 74FCT16373ATPVG carries MSL 3 (168 hours), while most substitutes carry MSL 1 (Unlimited). Lower MSL ratings reduce the risk of moisture-induced failures during storage and assembly operations, particularly in humid environments.

Q: Is the CY74FCT162373ATPVC recommended over other substitutes?

A: CY74FCT162373ATPVC is recommended as the primary substitute due to its active product status, ensuring continued availability and manufacturing support. However, all identified substitutes meet the functional and electrical requirements of the original part. Selection should be based on inventory availability, lead time, and specific application requirements.

Q: Do all substitutes comply with RoHS regulations?

A: All identified substitutes carry ROHS3 compliance certification, matching the original part's environmental compliance status. This ensures compatibility with RoHS-regulated supply chains and end-use applications.
