Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74FCT162374ATPVG are grouped based on the following critical parameters that determine functional and mechanical compatibility:

Core Functional Parameters:

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

Package Compatibility:

• Primary package: 48-BSSOP (0.295", 7.50mm Width)
• Alternative package: 48-TFSOP (0.240", 6.10mm Width) — functionally equivalent with different physical dimensions

Performance Parameters:

• Max Propagation Delay: 6.5ns @ 5V, 50pF (baseline)
• Current - Output High, Low: 24mA, 24mA (baseline)
• Current - Quiescent (Iq): 500 µA (baseline)

Substitutes are classified into two categories:

1. Direct Equivalents — Identical functional and electrical specifications with same or compatible package
2. Enhanced Performance Alternatives — Superior electrical characteristics (lower propagation delay, higher output current, lower quiescent current) with compatible pinout and package

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Same Series, Same Performance):

74FCT162374ATPAG is the manufacturer-recommended equivalent from Renesas Electronics Corporation. It maintains identical electrical specifications (6.5ns propagation delay, 24mA output current, 500 µA quiescent current) and core functionality. The primary difference is package format: 48-TFSOP (0.240", 6.10mm Width) versus 48-BSSOP (0.295", 7.50mm Width). This substitute is suitable when PCB layout accommodates the narrower package footprint. MSL rating improves to 1 (Unlimited) from 3 (168 Hours), reducing moisture sensitivity handling requirements.

CY74FCT162374ATPVC from Cypress Semiconductor Corp is an active product with identical package (48-BSSOP) and functional specifications. This part maintains the same pinout, output configuration, and supply voltage range. Product status is Active, ensuring long-term availability. Input capacitance increases to 4.5 pF from 4.6 pF, which is within acceptable tolerance for most applications.

For Enhanced Performance (Higher Speed, Higher Output Current):

SN74ABT16374ADL and SN74ABT16374ADLR from Texas Instruments represent the 74ABT series alternative. These parts deliver superior electrical performance: 4.7ns maximum propagation delay (versus 6.5ns), 32mA/64mA output current (versus 24mA/24mA), and lower quiescent current of 2 mA (versus 500 µA). Both parts are Active products with ROHS3 compliance and MSL 1 (Unlimited). The primary distinction is packaging: SN74ABT16374ADL uses Tube packaging, while SN74ABT16374ADLR uses Tape & Reel (TR) packaging. These substitutes are appropriate for applications requiring faster switching performance and higher drive capability.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, consistent with the original part. All operate within the -40°C ~ 85°C temperature range and 4.5V ~ 5.5V supply voltage specification.

Frequently Asked Questions (FAQ)

Q: Can 74FCT162374ATPAG be used as a direct replacement for 74FCT162374ATPVG?

A: Yes. Both parts are from Renesas Electronics Corporation, share identical electrical specifications (6.5ns propagation delay, 24mA output current, 500 µA quiescent current), and maintain the same functional configuration (dual 8-bit D-type flip-flop with tri-state outputs). The package differs in physical dimensions: 48-TFSOP (0.240", 6.10mm Width) versus 48-BSSOP (0.295", 7.50mm Width). Substitution is valid if the PCB layout accommodates the narrower package footprint.

Q: What is the difference between CY74FCT162374ATPVC and the original 74FCT162374ATPVG?

A: CY74FCT162374ATPVC is manufactured by Cypress Semiconductor Corp and maintains identical package (48-BSSOP), pinout, and functional specifications. The part is Active (versus Obsolete), ensuring continued availability. Input capacitance increases from 4.6 pF to 4.5 pF. This difference is negligible for most digital logic applications and does not affect functional compatibility.

Q: When should SN74ABT16374ADL or SN74ABT16374ADLR be selected over the original part?

A: The 74ABT series substitutes deliver enhanced performance: 4.7ns propagation delay (28% faster than 6.5ns), higher output current (32mA/64mA versus 24mA/24mA), and lower quiescent current (2 mA versus 500 µA). These parts are appropriate for applications requiring faster switching speed, higher output drive capability, or reduced power consumption. Both are Active products with superior MSL rating (1 versus 3).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, consistent with the original 74FCT162374ATPVG.

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

A: The original part has MSL 3 (168 Hours), requiring moisture control during storage and handling. Substitute parts have MSL 1 (Unlimited), eliminating moisture sensitivity constraints. This simplifies supply chain management and reduces handling requirements.

Q: Can the 74ABT series parts be used interchangeably with 74FCT series parts?

A: The 74ABT series parts (SN74ABT16374ADL, SN74ABT16374ADLR) share identical pinout, package, and functional configuration with the 74FCT series. They are electrically compatible and can be used as direct substitutes. The 74ABT series delivers superior performance characteristics (faster propagation delay, higher output current, lower quiescent current) and is recommended for new designs or performance-critical applications.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in the following packages: 48-BSSOP (0.295", 7.50mm Width) — standard package matching the original part; 48-TFSOP (0.240", 6.10mm Width) — narrower package option for space-constrained layouts. All packages are surface mount compatible.
