CY74FCT162374CTPVC Equivalent & Substitute Parts

Part Overview

The CY74FCT162374CTPVC is a dual 8-bit D-type flip-flop logic integrated circuit manufactured by Texas Instruments, housed in a 48-BSSOP surface mount package. This component functions as a standard positive edge-triggered flip-flop with tri-state, non-inverted outputs, designed for digital logic applications requiring high-speed data storage and transfer.

The CY74FCT162374CTPVC carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT162374CTPVC are grouped based on strict electrical and mechanical compatibility criteria derived from the provided parameters:

Primary Substitution Criteria:

• Identical functional type: D-Type flip-flop with 2 elements, 8 bits per element
• Matching output configuration: Tri-state, non-inverted outputs
• Identical trigger mechanism: Positive edge-triggered
• Compatible package: 48-BSSOP surface mount form factor
• Matching operating temperature range: -40°C ~ 85°C

Substitute Categories:

Category 1: Direct Voltage-Compatible Substitutes (5V Supply) Parts maintaining the 4.5V ~ 5.5V supply voltage specification with identical functional parameters. These substitutes preserve the original electrical operating point.

Category 2: Voltage-Adaptive Substitute (3.3V Supply) The SN74ALVCH162374DLR operates at 1.65V ~ 3.6V supply voltage, requiring circuit redesign for voltage compatibility but offering lower power consumption and modern active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (5V Systems):

The 74FCT16374CTPVG (IDT) is the preferred direct substitute, offering active product status while maintaining the 4.5V ~ 5.5V supply voltage specification. This part provides the shortest propagation delay (5.2ns @ 5V, 50pF) among the 5V-compatible options and is available in bulk packaging.

The 74FCT16374ATPVG (Renesas) and 74FCT16374ATPVG8 (Renesas) are functionally equivalent alternatives with active product status. Both maintain 5V supply compatibility and identical functional parameters. The 74FCT16374ATPVG8 is available in Tape & Reel packaging, while the 74FCT16374ATPVG is supplied in Tube packaging.

For Low-Power Applications (3.3V Systems):

The SN74ALVCH162374DLR (Texas Instruments) is suitable only for designs operating at 1.65V ~ 3.6V supply voltage. This part offers significantly lower quiescent current (40 µA versus 500 µA) and higher clock frequency capability (150 MHz). Circuit redesign is required for voltage compatibility.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and operate across the -40°C ~ 85°C temperature range. The 74FCT16374 variants (Renesas and IDT) carry MSL-3 ratings (168 hours), compared to the MSL-1 rating of the original part and the SN74ALVCH162374DLR. MSL-3 components require controlled moisture exposure during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162374DLR be used as a direct replacement in a 5V circuit?

A: No. The SN74ALVCH162374DLR operates at 1.65V ~ 3.6V supply voltage, incompatible with 5V systems. Direct substitution requires circuit redesign including voltage regulation and signal level conversion.

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

A: Both parts are functionally identical with matching electrical specifications. The difference is packaging: 74FCT16374ATPVG is supplied in Tube, while 74FCT16374ATPVG8 is supplied in Tape & Reel (TR) format.

Q: Are all substitute parts pin-compatible with the CY74FCT162374CTPVC?

A: Yes. All substitute parts use the 48-BSSOP package with identical pinout configuration, enabling direct PCB-level replacement without layout modification.

Q: What does MSL-3 (168 hours) mean for the 74FCT16374 variants?

A: MSL-3 indicates the component can be exposed to ambient conditions of 30°C / 85% relative humidity for a maximum of 168 hours before soldering. Longer storage requires controlled dry-box conditions. The original CY74FCT162374CTPVC carries MSL-1 (unlimited exposure), requiring less stringent storage control.

Q: Which substitute offers the best performance in terms of propagation delay?

A: The 74FCT16374CTPVG (IDT) provides the shortest propagation delay at 5.2ns @ 5V, 50pF, followed by 74FCT16374ATPVG and 74FCT16374ATPVG8 at 6.5ns @ 5V, 50pF. The SN74ALVCH162374DLR achieves 4.6ns @ 3.3V, 50pF but operates at a different supply voltage.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: SN74ALVCH162374DLR (2100 pcs), 74FCT16374ATPVG (1700 pcs), 74FCT16374ATPVG8 (1097 pcs), and 74FCT16374CTPVG (1300 pcs). Availability should be confirmed with your component supplier for production quantities.
