Independent Circuits: 2 channels
Output Type: Tri-State
Voltage Supply Range: 1.65V ~ 3.6V
Propagation Delay: 2.1ns
Output Current: 24mA (High and Low)

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended Primary Substitutes):

SN74LVC16373ADLR, SN74LVC16373DLR, SN74LVC16373ADL, and SN74LVC16373DL from Texas Instruments are direct parametric equivalents to the 74LVC16373APVG. These parts maintain identical electrical specifications across all critical parameters: 2 independent 8:8 channels, 2.1ns propagation delay, 24mA output current, and -40°C to 85°C operating temperature range. All are classified as Active products with ROHS3 compliance and MSL 1 rating, providing superior long-term availability compared to the obsolete Renesas part.

Series Variant (74LVCH):

SN74LVCH16373ADLR and SN74LVCH16373ADL represent the 74LVCH series variant, maintaining identical electrical performance and package specifications. These parts are suitable for direct substitution where the 74LVCH series designation is acceptable within system design constraints.

Packaging Format Consideration:

74LVC16373APAG (Renesas) provides parametric equivalence with a different package footprint (48-TFSOP vs. 48-BSSOP). This part is suitable only for new designs where PCB layout accommodates the narrower 6.10mm package width. It is not recommended for direct replacement in existing 48-BSSOP footprints.

Non-Equivalent Alternative:

CLVC16373AMDLREP (Texas Instruments) differs in circuit configuration (1 independent circuit vs. 2) and propagation delay (1.3ns vs. 2.1ns). This part is not a direct substitute and is suitable only for applications requiring single-channel operation with faster propagation characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC16373DL as a direct replacement for 74LVC16373APVG?

A: Yes. Both parts share identical electrical specifications: 2 independent 8:8 channels, 2.1ns propagation delay, 24mA output current, 1.65V to 3.6V supply voltage, and -40°C to 85°C operating temperature. The primary difference is product status (Active vs. Obsolete) and packaging format (Tube vs. Tube), making SN74LVC16373DL a suitable direct replacement.

Q: What is the difference between 74LVC and 74LVCH series parts?

A: Both series maintain identical electrical specifications for the 16373 logic function. The 74LVCH designation indicates a variant within the same functional family. Parts from either series are interchangeable based on the electrical parameters provided.

Q: Why is CLVC16373AMDLREP listed if it is not a direct substitute?

A: CLVC16373AMDLREP is included because it shares the same base product number (74LVC16373) and package type (48-BSSOP). However, it differs in circuit configuration (1 channel vs. 2 channels) and propagation delay (1.3ns vs. 2.1ns). This part is suitable only for applications that require single-channel operation and can tolerate faster propagation characteristics.

Q: Does packaging format affect electrical compatibility?

A: No. Packaging format (Tube vs. Tape & Reel) does not affect electrical compatibility. The choice between formats depends on procurement and assembly requirements. However, physical package dimensions (48-BSSOP vs. 48-TFSOP) require PCB layout verification before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What does MSL rating indicate for component selection?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. The 74LVC16373APVG carries MSL 3 (168 hours), while all substitute parts carry MSL 1 (Unlimited). MSL 1 provides greater handling flexibility and reduced risk of moisture-related failures during assembly.
