74LVCU04AD,112 Equivalent & Substitute Parts

Part Overview

The 74LVCU04AD,112 is a 6-channel inverter logic IC manufactured by Nexperia USA Inc., housed in a 14-SO surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a supply voltage range of 1.2V to 3.6V with low quiescent current and standard propagation delay characteristics suitable for general-purpose logic inversion applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVCU04AD,112 are selected based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Logic Type: Inverter with 6 channels and 1 input per channel
• Package Type: 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Supply Voltage Range: Must encompass or overlap with 1.2V ~ 3.6V
• Output Current Capability: Minimum 24mA for both high and low states
• Propagation Delay: Maximum 5.2ns @ 3.3V, 50pF (allowing for slight performance variation)
• Operating Temperature: Minimum -40°C ~ 85°C coverage
• Compliance: ROHS3 compliant, MSL 1 (Unlimited)

All substitute parts listed maintain these electrical and mechanical parameters within acceptable engineering tolerances for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The Texas Instruments SN74LVCU04 series (SN74LVCU04AD, SN74LVCU04ADR, SN74LVCU04ADT) represents the most direct replacement for the obsolete 74LVCU04AD,112. These parts maintain identical output current specifications (24mA, 24mA), matching propagation delay performance (3.8ns @ 3.3V, 50pF), and are currently in active production status. All variants are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format: tube (AD), tape & reel (ADR), or tape & reel (ADT).

Secondary Substitutes (Active Status):

The onsemi MC74LCXU04 series (MC74LCXU04DG, MC74LCXU04DR2G) provides functional equivalence with slightly reduced output current capability (18mA high, 16mA low) and marginally increased propagation delay (3.6ns @ 3.3V, 50pF). These parts are active production items suitable for applications where the reduced output current and extended delay remain within system requirements. Both variants are ROHS3 compliant with MSL 1 rating.

Tertiary Substitute (Obsolete Status):

The onsemi 74LCX04M is obsolete and should be considered only when active alternatives are unavailable. While functionally compatible, its obsolete status limits long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74LVCU04AD,112 with any of the listed substitutes?

A: Yes, all listed substitutes maintain the same 14-SOIC package dimensions and core inverter functionality. However, verify that your application tolerates the parameter variations shown in the comparison table, particularly propagation delay and output current specifications.

Q: What is the difference between the Texas Instruments variants (SN74LVCU04AD, SN74LVCU04ADR, SN74LVCU04ADT)?

A: These are identical parts with different packaging formats. AD is supplied in tube packaging, while ADR and ADT are supplied in tape & reel format. Select based on your procurement and assembly requirements.

Q: Why do the onsemi MC74LCXU04 parts have lower output current ratings?

A: The MC74LCXU04 series uses a different internal design that reduces output current to 18mA (high) and 16mA (low) compared to the 24mA specification of the main part. This remains suitable for standard logic-level applications but may not support high-capacitance or heavily loaded outputs.

Q: Are all substitutes RoHS compliant?

A: Yes, all listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original 74LVCU04AD,112.

Q: What is the operating temperature difference between the main part and substitutes?

A: The 74LVCU04AD,112 operates to 125°C maximum, while all active substitutes operate to 85°C maximum. Applications requiring operation above 85°C cannot use the listed substitutes.

Q: Which substitute offers the best performance match?

A: The Texas Instruments SN74LVCU04 series (all variants) provides the closest electrical performance match with identical output current and near-identical propagation delay. These are recommended as primary replacements.
