Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI74FCT162374ATA is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Logic function: Dual 8-bit D-type flip-flop with positive edge trigger
• Output configuration: Tri-state, non-inverted outputs
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature: -40°C ~ 85°C
• Output current capability: Minimum 24mA (high and low)

Package Compatibility:

• Primary package: 48-TFSOP (0.240", 6.10mm Width) for direct pin-compatible substitution
• Alternative package: 48-BSSOP (0.295", 7.50mm Width) for mechanical redesign scenarios

Substitutes are grouped into two categories:

1. Direct Pin-Compatible Substitutes (48-TFSOP package): 74FCT162374ATPACT, 74FCT162374ATPAG, CY74FCT16374CTPACT
2. Functional Equivalents with Package Variation (48-BSSOP package): 74FCT16374ATPVG, 74FCT16374ATPVG8

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (48-TFSOP Package):

The 74FCT162374ATPACT (Cypress Semiconductor, Active status) is the primary recommended substitute. This part maintains identical electrical specifications and package footprint, ensuring direct PCB compatibility without layout modifications. Active product status ensures long-term availability and supply chain stability.

The 74FCT162374ATPAG (Renesas Electronics) provides an alternative with ROHS3 compliance and documented propagation delay specifications. However, this part is obsolete, limiting its suitability for new designs requiring extended product lifecycle support.

For Functional Equivalence with Package Variation (48-BSSOP Package):

The 74FCT16374ATPVG and 74FCT16374ATPVG8 (both Renesas Electronics, Active status) offer enhanced output current capability (32mA/64mA versus 24mA/24mA) and ROHS3 compliance. These parts require PCB redesign due to package width difference (7.50mm versus 6.10mm) but provide superior electrical performance and regulatory compliance. The 74FCT16374ATPVG8 is supplied in Tape & Reel format for high-volume applications.

For Legacy System Support:

The CY74FCT16374CTPACT (Texas Instruments, Obsolete) maintains 48-TFSOP package compatibility with enhanced output current capability. Obsolete status restricts this option to existing inventory or specialized sourcing channels.

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT16374ATPVG as a direct replacement for PI74FCT162374ATA?

A: The 74FCT16374ATPVG is functionally equivalent but uses a different package (48-BSSOP versus 48-TFSOP). Pin assignments differ due to package geometry, requiring PCB layout modifications. Direct socket substitution is not possible.

Q: What is the difference between 74FCT16374ATPVG and 74FCT16374ATPVG8?

A: Both parts are electrically identical with the same electrical specifications and package. The primary difference is packaging format: 74FCT16374ATPVG is supplied in Tube, while 74FCT16374ATPVG8 is supplied in Tape & Reel (TR). Selection depends on assembly process requirements and order quantities.

Q: Why does 74FCT162374ATPACT show "Not specified" for propagation delay?

A: The propagation delay specification is not provided in the available technical documentation for this part. Contact the manufacturer for detailed timing specifications if critical path timing is a design requirement.

Q: Is the PI74FCT162374ATA RoHS compliant?

A: No, the PI74FCT162374ATA is RoHS non-compliant. For applications requiring RoHS compliance, select 74FCT162374ATPAG, 74FCT16374ATPVG, 74FCT16374ATPVG8, or CY74FCT16374CTPACT, all of which are ROHS3 compliant.

Q: What is the difference in output current between the main part and substitute options?

A: The PI74FCT162374ATA provides 24mA output current (both high and low). The 74FCT16374ATPVG and 74FCT16374ATPVG8 provide higher output current capability at 32mA (high) and 64mA (low), suitable for applications requiring greater drive capability.

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

A: Yes, provided they meet the electrical requirements of your application. However, using a single part number across the design simplifies procurement, inventory management, and troubleshooting.
