Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select from active or compliant substitute parts: 74FCT16374ATPVG, 74FCT16374ATPVG8, CY74FCT162374ATPVC, CY74FCT162374CTPVC, CY74FCT162374TPVCT, CY74FCT16374ATPVCT, CY74FCT16374CTPVC, or CY74FCT16374TPVC. These parts carry ROHS3 Compliant or equivalent compliance status.

For Active Product Status: The Renesas Electronics Corporation parts 74FCT16374ATPVG and 74FCT16374ATPVG8 maintain active product status, ensuring long-term availability and manufacturer support. These parts feature enhanced output current capability (32mA/64mA) and reduced input capacitance (4.6 pF) compared to the original specification.

For Identical Electrical Specifications: Parts maintaining 24mA output current and 4.5 pF input capacitance include 74FCT162374CTPVCT, CY74FCT162374ATPVC, CY74FCT162374CTPVC, and CY74FCT162374TPVCT. These provide direct electrical equivalence to the PI74FCT162374ATV.

For Supply Chain Availability: CY74FCT162374ATPVC (Cypress Semiconductor Corp, 8463 Pcs) offers the highest inventory level among substitute options, followed by CY74FCT162374CTPVC (2940 Pcs) and CY74FCT162374TPVCT (1803 Pcs).

For Packaging Preference:

• Tape & Reel: 74FCT162374CTPVCT, 74FCT16374ATPVG8
• Tube: 74FCT16374ATPVG, CY74FCT162374CTPVC, CY74FCT16374CTPVC

Frequently Asked Questions (FAQ)

Q: Can I substitute the PI74FCT162374ATV with any of the listed parts?

A: All listed parts meet the core electrical and mechanical compatibility criteria: dual 8-bit D-type flip-flop architecture, tri-state non-inverted outputs, positive edge trigger, 4.5V–5.5V supply voltage, -40°C to 85°C operating temperature, and 48-BSSOP surface mount package. Direct substitution is electrically and mechanically valid for all listed parts.

Q: What is the difference between 74FCT162374 and 74FCT16374 base part numbers?

A: Both designations refer to functionally equivalent dual 8-bit D-type flip-flops within the 74FCT logic family. The difference lies in manufacturer-specific naming conventions and internal design variations. Both are compatible substitutes for the PI74FCT162374ATV based on provided electrical and mechanical parameters.

Q: Are there differences in output current capability between substitute parts?

A: Yes. The PI74FCT162374ATV and most substitute parts specify 24mA output current (high and low). However, 74FCT16374ATPVG, 74FCT16374ATPVG8, CY74FCT16374ATPVCT, CY74FCT16374CTPVC, and CY74FCT16374TPVC provide higher output current: 32mA high and 64mA low. This represents enhanced drive capability and is acceptable for applications requiring the original 24mA specification.

Q: What is the significance of RoHS compliance status?

A: The PI74FCT162374ATV is RoHS non-compliant. Most substitute parts carry ROHS3 Compliant status, indicating compliance with Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements, select ROHS3 Compliant alternatives.

Q: Does product status (Active vs. Obsolete) affect substitution?

A: Product status indicates manufacturer support and long-term availability. Active parts (74FCT16374ATPVG and 74FCT16374ATPVG8 from Renesas) offer extended availability and manufacturer support. Obsolete parts remain functionally equivalent but may face future supply constraints. For new designs or long-term production, prioritize active parts.

Q: How do packaging options affect part selection?

A: Packaging options (Tape & Reel, Tube, Cut Tape & Digi-Reel, Bulk) affect handling, storage, and assembly processes but do not alter electrical or mechanical compatibility. Select packaging based on production volume and assembly equipment requirements.

Q: What is the impact of input capacitance variation (4.5 pF vs. 4.6 pF)?

A: Input capacitance affects circuit loading and signal integrity at high frequencies. The 74FCT16374ATPVG and 74FCT16374ATPVG8 specify 4.6 pF, representing reduced capacitive loading compared to the original 4.5 pF specification. This is a performance enhancement and does not compromise compatibility.

Q: Can I mix different substitute parts in the same application?

A: Yes. All substitute parts meet the same electrical and mechanical specifications for the core flip-flop function. Mixing parts with different output current ratings (24mA vs. 32mA/64mA) or input capacitance values (4.5 pF vs. 4.6 pF) is acceptable provided the circuit design accommodates the performance range.
