CLVCH16T245MDGVREP Equivalent & Substitute Parts

Part Overview

The CLVCH16T245MDGVREP is a translation transceiver logic IC manufactured by Texas Instruments, part of the 74LVCH series. This device functions as a bidirectional translator with 2 elements, 8 bits per element, and 3-state output capability in a 48-TVSOP package. The part is currently active in production with 1152 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible logic families with equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLVCH16T245MDGVREP is determined by the following critical parameters:

• Logic function: Translation Transceiver with 2 elements, 8 bits per element
• Output configuration: 3-State output
• Package type: 48-pin surface mount (TFSOP/TSSOP variants)
• Electrical compatibility: Supply voltage range, output current capability, and operating temperature range

Substitute parts are grouped into two categories:

Parametric Equivalents (Same Series, Same Packaging Format): Parts that maintain identical electrical specifications and the same package footprint, differing only in packaging method (Tape & Reel vs. Cut Tape).

Manufacturer Recommended Alternatives (Different Series, Compatible Specifications): Parts from different logic families (74LVC, 74AVC, 74VCX) that provide equivalent functionality with compatible electrical parameters, though some may have different supply voltage ranges or output current ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

SN74LVC16T245DGVR and SN74LVCH16T245DGVR are direct parametric equivalents to the CLVCH16T245MDGVREP. Both maintain identical electrical specifications, operating temperature range, and package footprint. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Both are active products with ROHS3 compliance and MSL 1 rating. These parts are suitable for direct substitution without circuit redesign.

Alternative Substitutes (Conditional Use):

The 74AVC16T245DGV,118 and 74AVC16T245DGG,118 from Nexperia provide equivalent translation transceiver functionality with reduced output current (12mA versus 32mA) and a narrower supply voltage range (0.8V ~ 3.6V versus 1.65V ~ 5.5V). These parts are suitable only when circuit design accommodates the lower supply voltage range and reduced output current capability. Both are active products with extended operating temperature range (-40°C ~ 125°C).

The 74VCX163245MTDX from onsemi is marked as obsolete and should be avoided for new designs. While it provides compatible functionality, its obsolete status and MSL 2 rating make it unsuitable for long-term supply chain reliability.

Packaging Considerations:

The 74AVC16T245DGG,118 and 74VCX163245MTDX feature a wider package footprint (0.240", 6.10mm Width) compared to the primary part (0.173", 4.40mm Width). PCB layout modifications may be required for these substitutes.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC16T245DGVR be used as a direct replacement for CLVCH16T245MDGVREP?

A: Yes. Both parts are from Texas Instruments, maintain identical electrical specifications including 32mA output current and 1.65V ~ 5.5V supply voltage range, and share the same 48-TFSOP package footprint. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). No circuit modifications are required.

Q: What are the limitations of using 74AVC16T245DGV,118 as a substitute?

A: The 74AVC16T245DGV,118 has reduced output current capability (12mA versus 32mA) and a narrower supply voltage range (0.8V ~ 3.6V versus 1.65V ~ 5.5V). Substitution is only valid if the circuit design operates within these reduced specifications. The part is suitable for lower-power applications but not for designs requiring the full 32mA output current or extended voltage range of the original part.

Q: Why is 74VCX163245MTDX listed as a substitute if it is obsolete?

A: The 74VCX163245MTDX is included in the manufacturer's substitute list but carries an obsolete product status. While it provides equivalent translation transceiver functionality, its obsolete designation indicates discontinued production and potential supply chain unavailability. This part should not be selected for new designs and is listed only for reference in legacy system maintenance scenarios.

Q: Are there package footprint differences between substitute parts?

A: Yes. The CLVCH16T245MDGVREP, SN74LVC16T245DGVR, and SN74LVCH16T245DGVR all use a 48-TFSOP package with 0.173" width (4.40mm). The 74AVC16T245DGV,118, 74AVC16T245DGG,118, and 74VCX163245MTDX use a wider 48-TFSOP package with 0.240" width (6.10mm). PCB layout verification is required before substituting parts with different package widths.

Q: What is the significance of MSL rating differences?

A: The CLVCH16T245MDGVREP, SN74LVC16T245DGVR, and SN74LVCH16T245DGVR have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 74VCX163245MTDX has MSL 2 (1 Year), requiring controlled storage and handling within one year of manufacture. For applications with extended storage or high-humidity environments, MSL 1 rated parts are preferred.

Q: Can multiple substitute parts be used interchangeably in the same design?

A: No. While SN74LVC16T245DGVR and SN74LVCH16T245DGVR are fully interchangeable, the 74AVC series parts have different electrical specifications and should not be mixed with 74LVCH or 74LVC parts in the same circuit without verification that all design parameters accommodate the reduced output current and narrower voltage range of the 74AVC devices.
