• Trigger Type: Positive Edge
• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C

Electrical Parameters (Must Be Within Tolerance):

• Voltage - Supply: 2.7V ~ 3.6V

All identified substitute parts maintain functional equivalence across these parameters while differing only in manufacturer, product status, packaging format, or minor electrical characteristics within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SN74LVTH16374DGGR (Texas Instruments)

The SN74LVTH16374DGGR is the direct parametric equivalent to the CLVTH16374IDGGREP. Both parts share identical electrical specifications, including 160 MHz clock frequency, 4.5 ns propagation delay, and matching output current ratings. The SN74LVTH16374DGGR maintains active product status with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory alignment. This part is available in Tape & Reel packaging format.

Secondary Substitute: 74LVT16374MTDX (Fairchild Semiconductor)

The 74LVT16374MTDX provides functional equivalence with matching 160 MHz clock frequency and 4.5 ns propagation delay. Output current specifications align with the main part (32 mA, 64 mA). This part maintains active status and identical package geometry. Quiescent current differs at 5 mA versus 190 µA in the main part, representing lower standby power consumption. This part is available in Bulk packaging format.

Tertiary Substitutes: 74LVT162374DGG,118 and 74LVTH16374ADGG,18

Both parts maintain functional compatibility with slightly reduced clock frequency (150 MHz) and marginally increased propagation delay (5.3 ns and 5 ns respectively). The 74LVT162374DGG,118 (NXP USA Inc.) features reduced output current (12 mA, 12 mA) and lower quiescent current (120 µA). The 74LVTH16374ADGG,18 (Nexperia USA Inc.) maintains output current matching the main part with reduced quiescent current (120 µA). Both parts are active and available in standard packaging formats.

Compliance Considerations:

All substitute parts operate within the -40°C to 85°C temperature range and 2.7V to 3.6V supply voltage specification. Parts with ROHS3 compliance certification (SN74LVTH16374DGGR and 74LVTH16374ADGG,18) are preferred for applications requiring regulatory compliance documentation. MSL 1 rating ensures unlimited shelf life without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

Q: Can the CLVTH16374IDGGREP be directly replaced with SN74LVTH16374DGGR?

A: Yes. The SN74LVTH16374DGGR is a parametric equivalent with identical electrical specifications, package geometry, and functional characteristics. Both parts are 48-TFSOP surface mount dual 8-bit D-type flip-flops with tri-state outputs operating at 2.7V to 3.6V. The primary difference is product status (obsolete versus active) and packaging format (bulk versus Tape & Reel).

Q: What are the key differences between 74LVTH and 74LVT series substitutes?

A: Both series are low-voltage CMOS logic families compatible with 2.7V to 3.6V operation. The 74LVTH series (Texas Instruments, Nexperia) and 74LVT series (NXP, Fairchild) maintain functional equivalence in this application. Minor electrical variations exist in quiescent current and output drive capability, but all parts meet the core functional requirements of the CLVTH16374IDGGREP.

Q: Are there packaging format differences between substitute parts?

A: Yes. The main part and SN74LVTH16374DGGR are available in Tape & Reel format, while 74LVT162374DGG,118 and 74LVT16374MTDX are supplied in Bulk format. The 74LVTH16374ADGG,18 is available in Tape & Reel format. All parts use identical 48-TFSOP (0.240", 6.10mm Width) package geometry suitable for automated assembly.

Q: Which substitute part offers the lowest power consumption?

A: The 74LVT16374MTDX features the lowest quiescent current at 5 mA, compared to 190 µA in the main part and 120 µA in the 74LVT162374DGG,118 and 74LVTH16374ADGG,18. For applications prioritizing standby power efficiency, the 74LVT16374MTDX is the appropriate selection.

Q: Do all substitute parts meet RoHS compliance requirements?

A: ROHS3 compliance is explicitly specified for SN74LVTH16374DGGR and 74LVTH16374ADGG,18. Compliance status is not specified in the provided data for 74LVT162374DGG,118 and 74LVT16374MTDX. Verify compliance documentation with the respective manufacturers for applications requiring regulatory certification.

Q: What is the significance of MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements prior to soldering. Parts with MSL 1 rating (CLVTH16374IDGGREP, SN74LVTH16374DGGR, and 74LVTH16374ADGG,18) offer simplified inventory management and reduced handling constraints compared to higher MSL classifications.

Q: Can propagation delay differences affect circuit timing?

A: The main part and most substitutes specify 4.5 ns propagation delay at 3.3V with 50 pF load. The 74LVT162374DGG,118 and 74LVTH16374ADGG,18 specify 5.3 ns and 5 ns respectively. For timing-critical applications, verify that the 0.5 to 0.8 ns increase remains within system timing margins before selection.
