Engineering Selection Recommendations

Both Texas Instruments substitute parts—SN74ALVTH16374DL and SN74ALVTH16374DLR—provide direct functional and electrical equivalence to the obsolete NXP 74ALVT16374DL,112. Selection between these two Texas Instruments options depends on packaging and supply chain requirements:

SN74ALVTH16374DL: Supplied in Tube packaging, suitable for standard component handling and storage
SN74ALVTH16374DLR: Supplied in Cut Tape (CT) & Digi-Reel® packaging, optimized for automated assembly and high-volume production environments

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The 74ALVTH series from Texas Instruments is the manufacturer-recommended substitute for the obsolete 74ALVT series from NXP.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVTH16374DL and SN74ALVTH16374DLR be used interchangeably?

A: Yes. Both parts are electrically and functionally identical. The difference lies in packaging format: Tube versus Cut Tape & Digi-Reel®. Selection depends on assembly process requirements and inventory management practices.

Q: What is the primary difference between the original NXP part and the Texas Instruments substitutes?

A: The original 74ALVT16374DL,112 from NXP and the substitute 74ALVTH series from Texas Instruments differ in manufacturer and series designation. All electrical parameters, clock frequency, propagation delay, voltage supply range, and package specifications remain identical, ensuring direct substitution capability.

Q: Are there any output current differences between the main part and substitutes?

A: The 74ALVT16374DL,112 specifies output current as 8mA/24mA and 32mA/64mA. The SN74ALVTH16374DL specifies 8mA/8mA, while the SN74ALVTH16374DLR specifies 8mA/24mA and 32mA/64mA. Verify output current requirements for your specific application before selection.

Q: Is the 48-BSSOP package footprint identical across all three parts?

A: Yes. All three parts use the 48-BSSOP (0.295", 7.50mm Width) surface mount package with identical mechanical specifications, enabling direct PCB layout compatibility.

Q: Do these parts require any special handling or storage considerations?

A: All parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard ESD precautions for logic ICs apply.
