74FCT16374ATPVG8 Equivalent & Substitute Parts

Part Overview

The 74FCT16374ATPVG8 is a dual 8-bit D-type flip-flop logic integrated circuit manufactured by Renesas Electronics Corporation. This device features tri-state, non-inverted outputs and operates across the 4.5V to 5.5V supply voltage range with a maximum propagation delay of 6.5ns at 5V with 50pF load. The part is currently in active product status and is ROHS3 compliant. Substitute parts are necessary when the primary part becomes unavailable due to inventory constraints, manufacturing discontinuation, or specific packaging requirements for production workflows.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CY74FCT162374ATPVC and SN74ABT16374ADL / SN74ABT16374ADLR are the preferred substitutes. CY74FCT162374ATPVC maintains active product status with the highest inventory availability (8463 pcs) and is ROHS3 compliant. The SN74ABT16374 series (both ADL and ADLR variants) offers superior performance with faster propagation delay (4.7ns versus 6.5ns) and active product status, though with higher quiescent current (2 mA versus 500 µA). Both options are suitable for direct replacement in applications where the 48-BSSOP package footprint is maintained.

Secondary Substitutes (Obsolete Product Status):

CY74FCT16374ATPVCT, CY74FCT16374CTPVC, and CY74FCT16374TPVC are obsolete but available in inventory. These parts maintain electrical compatibility with the main part and are suitable for applications where long-term availability is not a constraint. CY74FCT16374ATPVCT offers the closest electrical match with identical output current specifications (32mA / 64mA).

Packaging Considerations:

The main part is supplied in Tape & Reel (TR) format. Substitutes are available in multiple packaging formats: Cut Tape (CT), Tube, and Bulk. Selection should align with production workflow requirements and minimum order quantities.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, consistent with the main part. MSL ratings vary; substitutes with MSL 1 (Unlimited) provide superior moisture handling compared to the main part's MSL 3 (168 Hours).

Frequently Asked Questions (FAQ)

Q: Can I use SN74ABT16374ADLR as a direct replacement for 74FCT16374ATPVG8?

A: Yes. The SN74ABT16374ADLR meets all mandatory electrical and mechanical parameters. It features identical pin configuration, package type (48-BSSOP), output type (tri-state, non-inverted), and operating temperature range. The faster propagation delay (4.7ns versus 6.5ns) and higher quiescent current (2 mA versus 500 µA) are within acceptable substitution parameters.

Q: What is the difference between CY74FCT16374ATPVCT and CY74FCT16374CTPVC?

A: Both parts are electrically identical with matching output current specifications (32mA / 64mA) and identical propagation delay characteristics. The primary difference is packaging format: CY74FCT16374ATPVCT is supplied in Cut Tape (CT) & Digi-Reel format, while CY74FCT16374CTPVC is supplied in Tube format. Both are obsolete products.

Q: Why does CY74FCT162374ATPVC show lower output current (24mA / 24mA) compared to the main part?

A: CY74FCT162374ATPVC is a valid substitute because its output current specification (24mA / 24mA) exceeds the minimum required current for the application. The lower specification indicates reduced output drive capability, which is acceptable for circuits designed to operate within these parameters. This part is currently active and has the highest inventory availability.

Q: Is MSL rating important when selecting a substitute?

A: MSL rating affects moisture sensitivity during storage and handling. The main part has MSL 3 (168 Hours), while most substitutes have MSL 1 (Unlimited). MSL 1 provides superior moisture tolerance and is preferable for long-term storage or humid environments. However, both ratings are acceptable for standard manufacturing processes.

Q: Can I mix packaging formats in production?

A: Yes. All substitute parts use the same 48-BSSOP package footprint and are compatible with identical PCB layouts. Packaging format (Tape & Reel, Cut Tape, Tube, or Bulk) affects only the supply method and does not impact electrical or mechanical compatibility.

Q: What is the significance of "Obsolete" product status for substitute parts?

A: Obsolete status indicates the manufacturer has discontinued active production. However, obsolete parts with confirmed inventory availability remain electrically and mechanically compatible. Selection of obsolete substitutes should consider long-term supply chain requirements and inventory depletion timelines.
