74LVCU04APW,112 Equivalent & Substitute Parts

Part Overview

The 74LVCU04APW,112 is a 6-channel inverter logic IC manufactured by Nexperia USA Inc. in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74LVCU series operates across a wide supply voltage range of 1.2V to 3.6V, making it suitable for low-voltage digital applications requiring signal inversion across multiple channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVCU04APW,112 is determined by the following core parameters:

Functional Equivalence: All substitute parts must maintain 6-channel inverter topology with single input configuration and identical logic function.

Package Compatibility: Primary substitutes use 14-TSSOP packaging (0.173", 4.40mm width) for direct board-level compatibility. Secondary substitutes in 14-SSOP and 14-TVSOP packages require PCB layout verification due to dimensional differences.

Electrical Operating Range: Substitute parts must support the application's supply voltage requirements. The main part operates 1.2V ~ 3.6V; substitutes operating 1.65V ~ 3.6V are compatible with applications not requiring sub-1.65V operation.

Output Drive Capability: All substitutes maintain 24mA output drive (high and low), ensuring equivalent load-driving performance.

Propagation Delay: Substitutes with propagation delays up to 3.8ns at 3.3V and 50pF load remain functionally equivalent for timing-non-critical applications.

Temperature Range: Substitutes rated -40°C ~ 85°C are compatible with applications not requiring the extended 125°C upper limit.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

SN74LVCU04APWR and SN74LVCU04APW from Texas Instruments are the preferred substitutes. Both maintain identical 14-TSSOP packaging, matching pinout and board layout requirements. These parts are in active production status, ensuring long-term availability and supply chain stability. The Texas Instruments 74LVCU series shares the same base product number and electrical characteristics, with reduced quiescent current (10 µA vs. 40 µA) and slightly extended propagation delay (3.8ns vs. 2ns). Both are ROHS3 compliant with unlimited moisture sensitivity rating.

Secondary Substitutes (Package Variant):

SN74LVCU04ADBR uses 14-SSOP packaging (0.209", 5.30mm width) instead of 14-TSSOP, requiring PCB layout modification. SN74LVCU04ADGVR uses 14-TFSOP packaging, also requiring layout verification. Both maintain identical electrical performance to the primary substitutes and are suitable when PCB redesign is acceptable.

Cross-Series Substitute (Voltage Consideration):

MC74LCXU04DTR2G from onsemi operates at 2V ~ 3.6V minimum supply voltage, restricting use to applications not requiring 1.2V ~ 1.65V operation. This part exhibits lower output drive capability (18mA/16mA vs. 24mA/24mA) and is suitable only when supply voltage constraints are not limiting factors.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74LVCU04ADBR replace 74LVCU04APW,112 directly on the PCB?

A: SN74LVCU04ADBR uses 14-SSOP packaging (0.209", 5.30mm width) versus the original 14-TSSOP (0.173", 4.40mm width). Direct board replacement is not possible without PCB layout modification. Pin pitch and spacing differ between packages.

Q: What is the difference between SN74LVCU04APWR and SN74LVCU04APW?

A: Both parts are electrically identical with matching 14-TSSOP packaging. The primary difference is packaging format: APWR is supplied in Tape & Reel (TR) format for automated assembly, while APW is supplied in Tube format for manual handling. Select based on assembly process requirements.

Q: Is MC74LCXU04DTR2G suitable for all applications using 74LVCU04APW,112?

A: MC74LCXU04DTR2G operates at 2V ~ 3.6V minimum supply voltage, making it incompatible with applications requiring 1.2V ~ 1.65V operation. Additionally, output drive current is reduced (18mA/16mA vs. 24mA/24mA). Verify supply voltage and load requirements before selection.

Q: Why does the substitute part have lower quiescent current?

A: Texas Instruments 74LVCU series parts (10 µA quiescent) represent improved manufacturing technology compared to the Nexperia original (40 µA). Lower quiescent current reduces power consumption without affecting functional performance, providing a design benefit in the substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original 74LVCU04APW,112.

Q: What is the impact of 3.8ns propagation delay versus 2ns in the original part?

A: The 1.8ns increase in propagation delay is negligible for most digital logic applications. Applications with timing-critical signal paths operating near maximum frequency limits should evaluate the impact on system timing margins before substitution.

Q: Can I use MC74LCXU04DTR2G in a 1.2V supply application?

A: No. MC74LCXU04DTR2G minimum supply voltage is 2V. Applications requiring 1.2V ~ 1.65V operation must use Texas Instruments SN74LVCU04 variants, which support the full 1.65V ~ 3.6V range.
