74FCT162823CTPVG Equivalent & Substitute Parts

Part Overview

The 74FCT162823CTPVG is a dual 9-bit D-type flip-flop logic integrated circuit manufactured by Renesas Electronics Corporation in a 56-BSSOP surface mount package. This component functions as a master reset flip-flop with tri-state, non-inverted outputs, designed for high-speed digital logic applications requiring edge-triggered data capture and storage.

The 74FCT162823CTPVG currently holds Last Time Buy status, indicating that Renesas has discontinued or will discontinue production. This status necessitates identification of functionally equivalent substitute components to ensure design continuity and procurement availability for new production runs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74FCT162823CTPVG is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Dual 9-bit D-type flip-flop with positive edge trigger and master reset function
• Output Configuration: Tri-state, non-inverted outputs
• Electrical Specifications: Supply voltage range 4.5V ~ 5.5V, operating temperature -40°C ~ 85°C
• Package Compatibility: 56-BSSOP surface mount package (0.295", 7.50mm width)
• Propagation Delay Performance: Maximum propagation delay specifications at specified load conditions
• Output Drive Capability: Current sourcing and sinking capacity

The identified substitute parts maintain functional and electrical equivalence within the allowed parameter tolerances for this logic device category. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions based on availability and lifecycle stage.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CY74FCT162823CTPVC (Cypress Semiconductor)

The CY74FCT162823CTPVC is the manufacturer-recommended substitute with Active product status, ensuring long-term availability and supply chain stability. This part maintains electrical equivalence with output drive specifications matching the original 74FCT162823CTPVG (24mA/24mA). The Cypress variant offers superior moisture handling with MSL 1 rating compared to the original MSL 3 specification, reducing moisture-related field failures in storage and handling. However, this part carries RoHS non-compliant status, which may impact procurement for applications requiring full RoHS3 compliance.

Secondary Substitutes: CY74FCT16823CTPVC and CY74FCT16823CTPVCT (Texas Instruments)

Both Texas Instruments variants maintain functional equivalence and ROHS3 compliance but carry Obsolete product status. These parts feature enhanced output drive capability (32mA/64mA) and superior moisture sensitivity (MSL 1), providing performance margin in high-current applications. The CY74FCT16823CTPVCT is supplied in Cut Tape & Digi-Reel packaging, while CY74FCT16823CTPVC is supplied in Tube packaging. Propagation delay specifications are relaxed to 12.5ns compared to the original 8ns specification.

Compliance Considerations

Selection between substitutes depends on RoHS compliance requirements. For applications requiring ROHS3 compliance, the Texas Instruments variants are preferred despite Obsolete status. For applications where RoHS compliance is not mandated, the Cypress CY74FCT162823CTPVC offers the best long-term availability and supply security.

Frequently Asked Questions (FAQ)

Q: Can the CY74FCT162823CTPVC be used as a direct replacement for the 74FCT162823CTPVG?

A: The CY74FCT162823CTPVC is functionally equivalent and electrically compatible for applications where RoHS non-compliance is acceptable. Both parts share identical logic architecture, output configuration, supply voltage range, and operating temperature specifications. The primary difference is RoHS compliance status. Verify your application's compliance requirements before substitution.

Q: What is the significance of the propagation delay difference between the original part (8ns) and the Texas Instruments substitutes (12.5ns)?

A: The 4.5ns difference in maximum propagation delay represents a relaxed specification in the substitute parts. For most digital logic applications, this difference is not functionally significant. However, in timing-critical applications with tight setup and hold time requirements, this specification difference should be evaluated against system timing margins.

Q: Why do the Texas Instruments substitutes have higher output drive capability (32mA/64mA) compared to the original (24mA/24mA)?

A: The enhanced output drive specifications in the Texas Instruments variants provide additional current sourcing and sinking capacity. This represents a performance enhancement that maintains backward compatibility while offering improved drive capability for heavily loaded output nets.

Q: Are all substitute parts available in the same 56-BSSOP package?

A: All identified substitute parts are manufactured in the 56-BSSOP (0.295", 7.50mm width) surface mount package, ensuring mechanical and electrical compatibility with existing PCB designs. Packaging format differs by supplier: Cypress supplies in Bulk, Texas Instruments supplies in Tube or Cut Tape & Digi-Reel formats.

Q: What does MSL 1 (Unlimited) mean compared to MSL 3 (168 Hours)?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. MSL 3 (168 Hours) requires baking before reflow if storage exceeds 168 hours in high-humidity conditions. MSL 1 (Unlimited) has no moisture sensitivity restrictions, simplifying inventory management and reducing field failure risk from moisture absorption.

Q: Should I select the Obsolete Texas Instruments parts or the Active Cypress part?

A: For new designs, the Active Cypress CY74FCT162823CTPVC is preferred for long-term supply security. For legacy system maintenance where RoHS compliance is not required, the Cypress part is the optimal choice. Texas Instruments substitutes should be considered only when RoHS3 compliance is mandatory and current inventory of compliant alternatives is exhausted.
