Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ALVT162240DGG,51 is determined by the following critical parameters:

• Logic function: Buffer, Inverting with 4 elements and 4 bits per element
• Output configuration: 3-State output capability
• Supply voltage compatibility: 2.3V ~ 3.6V range
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount
• Package compatibility: 48-pin TFSOP or equivalent 48-pin packages (SSOP, TVSOP)

The substitute parts listed below maintain functional equivalence through identical logic configuration, voltage specifications, and temperature ratings. Package variations (TFSOP, SSOP, TVSOP) are acceptable substitutes provided the pin count and electrical characteristics remain consistent. Output current capabilities may vary between substitutes while maintaining functional compatibility within the specified voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence with the 74ALVT162240DGG,51 across the specified electrical and thermal operating ranges. Selection among substitutes should be based on the following factors:

Package Compatibility: The SN74ALVTH16240GR and SN74ALVTH16240VR maintain the same 48-TFSOP package footprint as the original part, requiring no PCB layout modifications. The SN74ALVTH16240DL and SN74ALVTH16240DLR use a 48-BSSOP package with different pitch and width specifications, necessitating PCB redesign if package-to-pad compatibility is critical.

Compliance and Certification: All substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status. The Texas Instruments substitutes feature improved moisture sensitivity ratings (MSL 1 vs. MSL 3), providing enhanced reliability in humid storage and operational environments.

Output Current Capability: The substitute parts deliver higher output current (32mA high, 64mA low) compared to the original part (12mA, 12mA). This increased drive capability is functionally compatible and does not introduce incompatibility with existing designs.

Availability and Product Status: All substitute parts are currently in stock. The SN74ALVTH16240GR and SN74ALVTH16240DL are listed as obsolete, while SN74ALVTH16240DLR and SN74ALVTH16240VR are discontinued at DiGi Electronics, indicating limited long-term availability across all options.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVTH16240 series directly replace the 74ALVT162240DGG,51?

A: Yes. The SN74ALVTH16240 series maintains identical logic function, element count, bit configuration, output type, supply voltage range, and operating temperature specifications. The substitutes are functionally equivalent within the specified electrical parameters.

Q: What is the difference between the package options among the substitute parts?

A: The SN74ALVTH16240GR uses a 48-TFSOP package (0.240" width, 6.10mm) matching the original part's footprint. The SN74ALVTH16240DL and SN74ALVTH16240DLR use a 48-BSSOP package (0.295" width, 7.50mm) with wider pitch. The SN74ALVTH16240VR uses a 48-TFSOP package with reduced width (0.173", 4.40mm). Package selection depends on PCB layout constraints and available board space.

Q: Are there differences in output current between the original and substitute parts?

A: Yes. The original 74ALVT162240DGG,51 provides 12mA output current (both high and low). The Texas Instruments substitutes provide 32mA high and 64mA low output current. This increased capability is compatible with existing designs and does not create functional incompatibility.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The original part has MSL 3 (168 hours), while all substitute parts have MSL 1 (unlimited). MSL rating indicates the maximum time a component can be exposed to moisture before soldering. Lower MSL values provide greater flexibility in storage and handling without requiring baking procedures prior to assembly.

Q: Which substitute part should be selected for new designs?

A: Selection should prioritize package compatibility with existing PCB layouts. For footprint-compatible designs, the SN74ALVTH16240GR is recommended due to matching 48-TFSOP package dimensions. For designs without package constraints, any substitute part is functionally equivalent based on the provided electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory compliance status of the original 74ALVT162240DGG,51.
