Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT16260DGG,118 is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 56-TFSOP (0.240", 6.10mm Width) surface mount package to ensure PCB layout and assembly compatibility.
• Circuit Configuration: The 12:24 multiplexing circuit must be maintained to preserve functional equivalence.
• Output Type: Tri-state output configuration must be retained for signal bus compatibility.
• Operating Temperature Range: The -40°C to 85°C operating range must be supported.
• Supply Voltage Compatibility: The substitute part must operate within or encompass the 2.3V to 2.7V supply voltage range of the original component.
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

The SN74ALVCH162260GR from Texas Instruments meets these substitution criteria through identical package geometry, matching circuit configuration, compatible tri-state output, and overlapping operational specifications.

• Functional Compatibility: Matching 12:24 circuit configuration and tri-state output preserve system functionality.
• Enhanced Performance Characteristics: The SN74ALVCH162260GR provides improved propagation delay (1ns versus 2.8ns) and expanded supply voltage range (1.65V ~ 3.6V), offering design flexibility for future applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162260GR be used as a direct replacement for the 74ALVT16260DGG,118?

A: Yes. Both components share identical package geometry (56-TFSOP), circuit configuration (12:24), output type (tri-state), and operating temperature range (-40°C to 85°C). The substitute part's supply voltage range (1.65V ~ 3.6V) encompasses the original part's range (2.3V ~ 2.7V), ensuring compatibility in existing designs.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), propagation delay (2.8ns versus 1ns), supply voltage range (2.3V ~ 2.7V versus 1.65V ~ 3.6V), and output current specifications (8mA/24mA versus 12mA/12mA). These differences favor the substitute part through improved performance and broader operational flexibility.

Q: Are there any PCB layout considerations when switching to the SN74ALVCH162260GR?

A: No PCB layout modifications are required. Both parts use the identical 56-TFSOP package with matching pin assignments and footprint dimensions (0.240", 6.10mm width).

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 74ALVT16260DGG,118 and SN74ALVCH162260GR are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: Why is the 74ALVT16260DGG,118 classified as obsolete?

A: The NXP part has reached end-of-life status. The SN74ALVCH162260GR from Texas Instruments remains in active production, providing continued availability and support for this logic function.
