Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ALVC16501MTDX is determined by strict equivalence across the following critical parameters:

• Logic Function: Universal bus transceiver with 18-bit configuration
• Electrical Specifications: Output current (24mA high/low), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C)
• Package Compatibility: 56-pin TSSOP or SSOP package variants
• Mounting Technology: Surface mount configuration

The identified substitute parts maintain functional and electrical equivalence to the original component. Packaging variations exist between substitute options, affecting board-level integration considerations.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments substitute parts (SN74ALVCH16501DGGR and SN74ALVCH16501DL) provide functional equivalence to the obsolete 74ALVC16501MTDX. The selection between these options depends on packaging requirements and compliance status.

SN74ALVCH16501DGGR maintains identical package dimensions (56-TFSOP, 0.240" width) to the original component, enabling direct board-level substitution without layout modifications. This part carries active product status and ROHS3 compliance certification.

SN74ALVCH16501DL provides the same electrical and functional specifications but uses a wider package variant (56-BSSOP, 0.295" width). This option requires board layout evaluation for physical fit. This part also maintains active product status and ROHS3 compliance certification.

Both substitute parts are REACH compliant and share identical electrical characteristics, supply voltage ranges, output current ratings, and operating temperature specifications with the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16501DGGR directly replace 74ALVC16501MTDX on existing PCBs?

A: Yes. Both components use the 56-TFSOP package with identical 0.240" width dimensions. Electrical specifications, pin configuration, and functional behavior are equivalent, enabling direct substitution without board redesign.

Q: What is the primary difference between the two Texas Instruments substitutes?

A: The SN74ALVCH16501DGGR uses a 56-TFSOP package (0.240" width), while the SN74ALVCH16501DL uses a 56-BSSOP package (0.295" width). Both maintain identical electrical performance and 18-bit universal bus transceiver functionality. Package selection depends on available board space and footprint compatibility.

Q: Are the substitute parts suitable for new designs?

A: Both SN74ALVCH16501DGGR and SN74ALVCH16501DL carry active product status from Texas Instruments, making them appropriate for new design implementations. Both parts meet ROHS3 compliance requirements.

Q: Do the substitute parts operate within the same voltage and temperature ranges?

A: Yes. All three components operate across 1.65V to 3.6V supply voltage and -40°C to 85°C temperature ranges. Output current specifications (24mA high/low) are identical across all variants.

Q: What packaging options are available for this 18-bit transceiver?

A: The 74ALVC16501MTDX is available in 56-TSSOP packaging. Substitute parts from Texas Instruments are available in 56-TFSOP (SN74ALVCH16501DGGR) and 56-BSSOP (SN74ALVCH16501DL) variants. All packages accommodate surface mount assembly.
