Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74FCT16374CTPVG8 are qualified based on the following core parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Type: D-Type flip-flop architecture
• Number of Elements: 2
• Number of Bits per Element: 8
• Output Type: Tri-State, Non-Inverted
• Trigger Type: Positive Edge
• Voltage Supply Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C (TA)

Mechanical Compatibility Criteria:

• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 48-SSOP

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99

Substitute parts meeting all these criteria are functionally interchangeable at the circuit level. Variations in propagation delay, output current ratings, quiescent current, input capacitance, and packaging format (Tube, Tape & Reel, Bulk, Cut Tape) do not affect core functional compatibility but may impact performance characteristics and procurement logistics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

SN74ABT16374ADL and SN74ABT16374ADLR are the preferred substitutes for the 74FCT16374CTPVG8. Both parts are manufactured by Texas Instruments, carry Active product status, and maintain full electrical and mechanical compatibility. The 74ABT series offers improved performance characteristics with lower propagation delay (4.7ns versus 5.2ns) and higher clock frequency capability (150 MHz). Both parts are ROHS3 compliant and REACH unaffected. The primary difference between these two is packaging format: SN74ABT16374ADL is supplied in Tube packaging, while SN74ABT16374ADLR is supplied in Tape & Reel format. Selection between these should be based on procurement and assembly requirements.

Secondary Substitutes (Obsolete Product Status):

CY74FCT162374ATPVC, manufactured by Cypress Semiconductor Corp, is an Active product that provides functional equivalence. This part maintains all core electrical and mechanical parameters but differs in output current ratings (24mA, 24mA versus 32mA, 64mA) and is supplied in Bulk packaging format.

CY74FCT16374CTPVC, CY74FCT162374CTPVC, CY74FCT16374ATPVCT, and CY74FCT16374TPVC are all Obsolete products from Texas Instruments and Cypress Semiconductor. While these parts maintain functional compatibility, their obsolete status limits their suitability for new designs or long-term supply assurance. These parts should be considered only when existing inventory is available or when design constraints require specific performance characteristics.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original 74FCT16374CTPVG8. Moisture Sensitivity Level (MSL) varies across substitutes; most obsolete variants carry MSL 1 (Unlimited), while the original part carries MSL 3 (168 Hours), indicating improved moisture handling in substitute parts.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74FCT16374CTPVG8 with SN74ABT16374ADLR without circuit modifications?

A: Yes. The SN74ABT16374ADLR maintains identical electrical specifications for supply voltage (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), package type (48-BSSOP), and functional architecture (dual 8-bit D-type flip-flop with positive edge trigger and tri-state outputs). The part is a direct pin-compatible substitute. The improved propagation delay (4.7ns versus 5.2ns) and higher clock frequency (150 MHz) represent performance enhancements that do not require circuit redesign.

Q: What is the difference between the 74FCT and 74ABT series?

A: Both series are standard TTL-compatible logic families with identical functional architecture and pin compatibility. The 74ABT series offers superior performance characteristics, including faster propagation delay and higher clock frequency capability. The 74ABT series also exhibits higher quiescent current (2 mA versus 500 µA), which may impact power consumption in low-power applications. Both series operate within the same supply voltage range (4.5V ~ 5.5V) and temperature range (-40°C ~ 85°C).

Q: Why do some substitute parts show "Not specified" for propagation delay?

A: Obsolete products from manufacturers may have incomplete technical documentation in current databases. The absence of specified propagation delay does not indicate incompatibility; it reflects data availability limitations for discontinued parts. For obsolete substitutes, functional compatibility is determined by matching core parameters: type, element count, bit width, output configuration, trigger type, voltage range, and package format.

Q: Does packaging format (Tube, Tape & Reel, Bulk) affect electrical performance?

A: No. Packaging format affects only procurement, storage, and assembly logistics. Electrical performance and functional characteristics remain identical regardless of whether a part is supplied in Tube, Tape & Reel, Bulk, or Cut Tape format. Selection should be based on manufacturing assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitutes are ROHS3 compliant except CY74FCT162374ATPVC, for which RoHS status is not specified in available documentation. For applications requiring verified ROHS3 compliance, SN74ABT16374ADL, SN74ABT16374ADLR, CY74FCT16374CTPVC, 74FCT162374CTPVCT, CY74FCT162374CTPVC, CY74FCT16374ATPVCT, and CY74FCT16374TPVC all carry explicit ROHS3 compliance certification.

Q: What is the significance of Moisture Sensitivity Level (MSL)?

A: MSL indicates the maximum time a component can be exposed to ambient moisture before soldering without risk of delamination or failure. The original 74FCT16374CTPVG8 carries MSL 3 (168 Hours), requiring controlled storage conditions. Most substitute parts carry MSL 1 (Unlimited), indicating superior moisture resistance and reduced storage constraints. This represents an improvement in handling and storage requirements for substitute parts.

Q: Can I use CY74FCT162374ATPVC as a substitute despite its Obsolete status?

A: CY74FCT162374ATPVC is the only Obsolete substitute with Active product status, indicating continued availability from Cypress Semiconductor. It maintains full functional compatibility and is REACH unaffected. However, Active status does not guarantee indefinite availability. For long-term supply assurance, SN74ABT16374ADL or SN74ABT16374ADLR are preferred due to their confirmed Active status with Texas Instruments.
