Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74VCX16501MTDX is determined by the following critical parameters:

• Logic Function: Universal bus transceiver with 18-bit configuration
• Package Compatibility: 56-TFSOP surface mount package with identical pin count and physical dimensions
• Electrical Specifications: Output current capability (24mA high/low), supply voltage range, and operating temperature range
• Pin Configuration: Identical pinout required for direct replacement without circuit modification

The SN74ALVCH16501DGGR from Texas Instruments meets these substitution criteria through matching logic function, package type, pin count, and electrical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVCH16501DGGR is a direct functional substitute for the 74VCX16501MTDX. Both components share identical logic architecture, pin configuration, package dimensions, and output current specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The SN74ALVCH16501DGGR operates at a minimum supply voltage of 1.65V compared to the 74VCX16501MTDX minimum of 1.4V. For applications requiring operation below 1.65V, the original 74VCX16501MTDX specification must be maintained. For standard applications operating within the 1.65V to 3.6V range, the Texas Instruments substitute provides equivalent electrical performance with the advantage of active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH16501DGGR be used as a direct replacement for the 74VCX16501MTDX?

A: Yes, for applications operating at supply voltages of 1.65V or higher. Both parts share identical pin configuration, package dimensions, logic function, and output current specifications. The substitute part is pin-compatible and requires no circuit modifications.

Q: What is the voltage difference between these parts?

A: The 74VCX16501MTDX operates from 1.4V to 3.6V, while the SN74ALVCH16501DGGR operates from 1.65V to 3.6V. Applications requiring operation below 1.65V must use the original onsemi part or identify an alternative substitute with lower minimum voltage specification.

Q: Are the package dimensions identical?

A: Yes. Both components use the 56-TFSOP package with 0.240" width and 6.10mm dimensions. No PCB layout modifications are required for substitution.

Q: What is the difference in product status?

A: The 74VCX16501MTDX is obsolete, while the SN74ALVCH16501DGGR is in active production. The active status of the substitute ensures continued availability and manufacturing support.

Q: Does the substitute part meet RoHS requirements?

A: The SN74ALVCH16501DGGR is ROHS3 compliant. RoHS status for the original 74VCX16501MTDX is not specified in the available documentation.
