Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVT16240DGG,112 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Logic Type: Buffer, Inverting
• Number of Elements: 4
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 32mA, 64mA
• Voltage - Supply: 2.3V ~ 2.7V, 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Package Considerations: Substitute parts are grouped by package type. The primary equivalent maintains the 48-TFSOP (0.240", 6.10mm Width) package. Alternative packages (48-BSSOP and 48-TVSOP) are available from the same base product family (74ALVTH16240) and provide electrical equivalence with different physical form factors.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent (Direct Replacement): SN74ALVTH16240GR from Texas Instruments is the closest functional equivalent, maintaining identical logic type (Buffer, Inverting), element configuration (4 elements, 4 bits per element), output characteristics (3-State, 32mA/64mA), voltage supply ranges (2.3V ~ 2.7V, 3V ~ 3.6V), and package form factor (48-TFSOP, 0.240", 6.10mm Width). This part is ROHS3 compliant with MSL 1 rating, matching the original specification.

Alternative Package Options: SN74ALVTH16240DL and SN74ALVTH16240DLR provide electrical equivalence with a wider 48-BSSOP package (0.295", 7.50mm Width). These are suitable for applications where PCB layout accommodates the larger package footprint. SN74ALVTH16240VR offers the narrowest package option (48-TFSOP, 0.173", 4.40mm Width) for space-constrained designs.

Limited Compatibility: SN74LVC646ADW differs in logic type (Transceiver, Non-Inverting), element configuration (1 element, 8 bits per element), and output current (24mA, 24mA). This part is not a direct functional equivalent and should only be considered if circuit topology permits non-inverting transceiver operation with modified bit-per-element architecture. This part maintains active product status.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVTH16240GR directly replace 74ALVT16240DGG,112 without PCB modification? A: Yes. SN74ALVTH16240GR maintains identical package dimensions (48-TFSOP, 0.240", 6.10mm Width), pin count, and electrical specifications. No PCB layout changes are required for direct substitution.

Q: What is the difference between the 48-TFSOP and 48-BSSOP packages? A: The 48-TFSOP package is 0.240" (6.10mm) wide, while the 48-BSSOP package is 0.295" (7.50mm) wide. Both are surface-mount packages with identical pin pitch. Package selection depends on available PCB real estate and design constraints.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (SN74ALVTH16240DL, SN74ALVTH16240DLR, SN74ALVTH16240GR, SN74ALVTH16240VR, and SN74LVC646ADW) are ROHS3 compliant with MSL 1 rating, matching the original part's environmental compliance.

Q: Why is SN74LVC646ADW listed as a substitute if it has different specifications? A: SN74LVC646ADW is included in the substitute list based on the original part's documented substitutes. However, it differs in logic type (Transceiver, Non-Inverting vs. Buffer, Inverting), element count (1 vs. 4), and bits per element (8 vs. 4). This part is suitable only for applications where circuit topology can accommodate these functional differences.

Q: What is the voltage supply range compatibility? A: The primary substitutes (SN74ALVTH series) operate across 2.3V ~ 2.7V and 3V ~ 3.6V supply ranges, identical to the original part. SN74LVC646ADW extends the lower voltage limit to 1.65V, providing broader voltage compatibility but with different functional characteristics.

Q: Are there inventory considerations for substitute selection? A: Inventory availability varies by part and supplier. SN74ALVTH16240VR has the highest documented inventory (3116 Pcs), while SN74ALVTH16240DLR has 959 Pcs. Availability should be confirmed with your component supplier for production planning.
