74FCT162374ETPVG Equivalent & Substitute Parts

Part Overview

The 74FCT162374ETPVG is a dual 8-bit D-type flip-flop logic integrated circuit manufactured by Renesas Electronics Corporation. This component features tri-state, non-inverted outputs and is housed in a 48-BSSOP surface mount package. The device is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The 74FCT series represents an earlier generation of high-speed CMOS logic, and active alternatives are available to maintain design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74FCT162374ETPVG is determined by strict alignment of the following critical parameters:

• Functional equivalence: D-type flip-flop configuration with 2 elements and 8 bits per element
• Output characteristics: Tri-state, non-inverted output topology
• Package compatibility: 48-BSSOP surface mount package with identical pin count and pitch
• Electrical specifications: Supply voltage range 4.5V ~ 5.5V, operating temperature -40°C ~ 85°C
• Trigger mechanism: Positive edge triggering
• Compliance requirements: ROHS3 compliance and EAR99 classification

The SN74ABT16374ADL from Texas Instruments satisfies all substitution criteria. While the 74ABT series represents a more advanced technology node with improved performance characteristics, it maintains full functional and pin-level compatibility with the 74FCT162374ETPVG within the specified electrical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The SN74ABT16374ADL is the direct functional substitute for the 74FCT162374ETPVG. Both devices are ROHS3 compliant and classified under EAR99 export control. The SN74ABT16374ADL carries active product status from Texas Instruments, ensuring long-term availability and supply chain stability compared to the obsolete 74FCT162374ETPVG.

The 74ABT series technology provides enhanced performance with higher output drive capability (32mA/64mA versus 24mA/24mA) and improved moisture sensitivity rating (MSL 1 versus MSL 3). These characteristics make the SN74ABT16374ADL suitable for applications requiring extended shelf life and higher current delivery without modification to existing PCB designs or signal integrity requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74ABT16374ADL be used as a direct replacement for the 74FCT162374ETPVG?

A: Yes. Both devices share identical pin configurations, package geometry (48-BSSOP), functional architecture (dual 8-bit D-type flip-flops with tri-state outputs), and electrical operating ranges (4.5V–5.5V supply, -40°C to 85°C). No PCB modifications or design changes are required.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), output drive current (24mA/24mA versus 32mA/64mA), propagation delay (3.7ns versus 4.7ns at 5V, 50pF), quiescent current (500µA versus 2mA), and moisture sensitivity level (MSL 3 versus MSL 1). These differences do not affect functional compatibility in standard applications.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The SN74ABT16374ADL's improved MSL rating (1 versus 3) provides additional reliability for long-term storage and handling.

Q: Does the package remain the same?

A: Yes. Both devices use the 48-BSSOP surface mount package with 0.295" width and 7.50mm body dimension. Pin pitch, lead spacing, and solder pad layouts are identical.

Q: What is the availability status of each part?

A: The 74FCT162374ETPVG is obsolete with limited remaining inventory. The SN74ABT16374ADL is an active product with established supply channels and ongoing manufacturing support from Texas Instruments.
