Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74VCX16245MTDX is determined by strict alignment of the following critical parameters:

Core Functional Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 85°C (TA)

Voltage Supply Compatibility: Substitute parts must support the full 1.2V to 3.6V supply voltage range of the 74VCX16245MTDX, or operate within a subset of this range that encompasses the application's operating voltage.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and EAR99 export classification.

The identified substitute parts are grouped into two categories: direct functional substitutes from alternative manufacturers (Renesas Electronics Corporation and Texas Instruments) and parametric equivalents from Nexperia USA Inc. that maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Recommended for New Designs):

The 74ALVC16245DGG,118 and 74ALVCH16245DGG,11 from Nexperia USA Inc. are parametric equivalents that maintain the full 1.2V to 3.6V supply voltage range of the original 74VCX16245MTDX. Both parts are in Active product status with unlimited moisture sensitivity rating and are available in Tape & Reel packaging. These components are suitable for direct substitution in applications requiring the extended low-voltage operating capability.

Functional Substitutes (Limited Voltage Range):

The Renesas Electronics Corporation parts (74ALVC16245PAG, 74ALVC16245PAG8, 74ALVCH16245PAG) and Texas Instruments parts (SN74ALVCH16245DGG, SN74ALVCH16245DGGR) are functional substitutes with identical logic functionality and package specifications. However, these parts operate within a reduced supply voltage range of 1.65V to 3.6V (Texas Instruments) or 2.7V to 3.6V (Renesas), which may limit their use in applications requiring operation below 1.65V. The Texas Instruments variants are in Active product status, while the Renesas parts are Obsolete.

Compliance Considerations:

All identified substitute parts maintain ROHS3 compliance and EAR99 export classification, consistent with the original 74VCX16245MTDX specifications.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVC16245PAG directly replace the 74VCX16245MTDX?

A: The 74ALVC16245PAG is functionally compatible in terms of logic operation, element count, bit width, and output type. However, it operates at a reduced supply voltage range of 2.7V to 3.6V compared to the 74VCX16245MTDX range of 1.2V to 3.6V. Substitution is valid only if your application operates within the 2.7V to 3.6V range.

Q: What is the difference between the Nexperia parametric equivalents and the Renesas/Texas Instruments substitutes?

A: The Nexperia parts (74ALVC16245DGG,118 and 74ALVCH16245DGG,11) maintain the full 1.2V to 3.6V supply voltage specification of the original part and are in Active product status. The Renesas and Texas Instruments alternatives operate at reduced minimum supply voltages (2.7V or 1.65V respectively) and the Renesas variants are Obsolete. For new designs, Nexperia parametric equivalents are preferred.

Q: Are all substitute parts available in the same package?

A: Yes, all identified substitute parts use the 48-TFSOP package with 0.240" width and 6.10mm dimensions, matching the original 74VCX16245MTDX package specification. Packaging formats vary (Tube, Cut Tape, Tape & Reel) but the physical package remains consistent.

Q: What is the moisture sensitivity difference between the original part and substitutes?

A: The 74VCX16245MTDX has MSL 2 (1 Year), while all substitute parts have MSL 1 (Unlimited). This indicates substitute parts have superior moisture resistance and longer shelf life without baking requirements.

Q: Which substitute should I select for a new design?

A: For new designs, select either 74ALVC16245DGG,118 or 74ALVCH16245DGG,11 from Nexperia. Both are in Active product status, maintain the full 1.2V to 3.6V supply voltage range, and offer unlimited moisture sensitivity. The choice between 74ALVC and 74ALVCH series depends on your specific application requirements for advanced bus hold or other functional features.

Q: Are there any compliance or export restrictions on these substitute parts?

A: All substitute parts maintain ROHS3 compliance and EAR99 export classification, identical to the original 74VCX16245MTDX. No additional compliance considerations apply to substitution.
