CLVTH16373IDLREP Equivalent & Substitute Parts

Part Overview

The CLVTH16373IDLREP is a 16-bit transparent D-latch logic integrated circuit manufactured by Texas Instruments in the 74LVTH series. This device functions as a 2-channel, 8:8 configuration with tri-state output capability, designed for bus driver and data latch applications requiring low-voltage operation. The part is currently in active production status with 974 units in stock.

Substitute parts are necessary when the original CLVTH16373IDLREP becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when sourcing from multiple suppliers is needed to meet supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLVTH16373IDLREP is determined by the following critical parameters:

• Logic Function: D-Type Transparent Latch with 2 independent circuits in 8:8 configuration
• Output Type: Tri-State capability
• Supply Voltage: 2.7V ~ 3.6V operating range
• Output Current Capability: 32mA (high) and 64mA (low) minimum
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package Compatibility: 48-pin SSOP/TSSOP variants

The identified substitute parts maintain functional equivalence across these core parameters. Variations in propagation delay time (2.9ns vs. 1.5ns), packaging width (7.50mm vs. 6.10mm), and product status do not prevent substitution when the application timing requirements and PCB layout accommodate these differences.

Parameter Comparison

Engineering Selection Recommendations

74LVT16373MTD (Fairchild Semiconductor): This substitute maintains active product status with higher inventory availability (2270 units). The part meets all functional and electrical requirements with improved propagation delay performance (1.5ns vs. 2.9ns). Packaging width reduction from 7.50mm to 6.10mm requires PCB layout verification. RoHS and MSL compliance information is not provided; verification with the supplier is necessary for applications with specific compliance requirements.

74LVT16373MTDX (onsemi): This substitute offers the highest inventory availability (9400 units) and maintains ROHS3 compliance with MSL Level 2 rating. The part is designated as Last Time Buy, indicating limited future availability. Propagation delay improvement (1.5ns) and package width reduction (6.10mm) apply as noted above. The MSL Level 2 rating requires controlled storage conditions (1-year shelf life) compared to the main part's unlimited storage capability.

Selection between substitutes should prioritize active product status and long-term availability unless supply constraints or specific application timing requirements dictate otherwise.

Frequently Asked Questions (FAQ)

Q: Can 74LVT16373MTD and 74LVT16373MTDX be used interchangeably with CLVTH16373IDLREP?

A: Both substitutes are functionally equivalent for applications where the core parameters (logic function, voltage range, output current, temperature range) are met. The primary differences are propagation delay (faster by 1.4ns), package width (narrower by 1.40mm), and product lifecycle status. PCB layout and timing analysis must confirm compatibility.

Q: What is the impact of the package width difference between 48-BSSOP and 48-TFSOP?

A: The 48-BSSOP (7.50mm) is wider than the 48-TFSOP (6.10mm) by 1.40mm. This affects PCB footprint dimensions and component placement. Designs using the narrower 48-TFSOP substitute require PCB layout modification. Pin pitch and electrical connectivity remain identical.

Q: Why does 74LVT16373MTDX have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part number. While currently available in high quantity (9400 units), future procurement will not be possible. This substitute is suitable for immediate needs but not recommended for long-term production planning.

Q: How does the MSL Level 2 rating of 74LVT16373MTDX affect handling?

A: MSL Level 2 requires storage at controlled humidity (≤60% RH) with a 1-year shelf life from the date of manufacture. The main part (MSL Level 1) has unlimited shelf life. Proper moisture control during storage and handling is necessary to prevent moisture absorption that could cause soldering defects.

Q: Are there compliance differences between the three parts?

A: The main part (CLVTH16373IDLREP) and 74LVT16373MTDX are confirmed ROHS3 compliant. The 74LVT16373MTD compliance status is not specified in available data. All three parts are REACH Unaffected and carry EAR99 ECCN classification. Verification with suppliers is recommended for applications with specific regulatory requirements.
