Engineering Selection Recommendations

Primary Recommendation: SN74ALVCH16240DGGR

The SN74ALVCH16240DGGR is the optimal substitute for the obsolete 74ALVC16240MTDX. This part maintains identical electrical specifications and package dimensions (48-TFSOP), ensuring direct compatibility. The component is manufactured by Texas Instruments with active product status and ROHS3 compliance, providing long-term availability and regulatory alignment.

Secondary Recommendation: SN74LVCH16240ADGGR

The SN74LVCH16240ADGGR offers equivalent electrical and mechanical specifications with the highest inventory availability (3200 Pcs). This Texas Instruments part is also active and ROHS3 compliant, with identical package configuration and electrical performance.

Alternative Consideration: SN74ALVCH16240DL

The SN74ALVCH16240DL provides functional equivalence with all electrical parameters matching the original part. However, the package variant (48-BSSOP with 0.295" width versus 48-TFSOP with 0.240" width) requires PCB layout verification before implementation. This part is supplied in tube packaging and maintains active status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16240DGGR be used as a direct replacement for 74ALVC16240MTDX?

A: Yes. Both parts share identical electrical specifications (4-element, 4-bit buffer with 3-state output, 24mA drive capability, 1.65V–3.6V supply range, -40°C to 85°C operating temperature) and the same package footprint (48-TFSOP). No circuit modifications are required.

Q: What is the difference between SN74ALVCH16240DGGR and SN74LVCH16240ADGGR?

A: Both parts are parametric equivalents with identical electrical performance and 48-TFSOP packaging. The primary differences are the manufacturer series designation (74ALVCH versus 74LVCH) and inventory availability. All electrical and mechanical parameters remain equivalent.

Q: Why is SN74ALVCH16240DL listed as an alternative if the package is different?

A: SN74ALVCH16240DL maintains all required electrical specifications and is functionally equivalent. The package variant (48-BSSOP versus 48-TFSOP) differs in body width (0.295" versus 0.240"), which may affect PCB layout compatibility. This part is suitable only if the PCB design accommodates the wider package footprint.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (SN74ALVCH16240DL, SN74ALVCH16240DGGR, and SN74LVCH16240ADGGR) are ROHS3 compliant. The original 74ALVC16240MTDX RoHS status was not specified in the provided data.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the package footprint is compatible with the PCB layout. SN74ALVCH16240DGGR and SN74LVCH16240ADGGR are direct footprint matches (48-TFSOP). SN74ALVCH16240DL requires verification of the wider 48-BSSOP footprint compatibility before implementation.
