74LVC245APW/AUJ Equivalent & Substitute Parts

Part Overview

The 74LVC245APW/AUJ is a non-inverting transceiver logic IC manufactured by NXP USA Inc., designed for 8-bit data bus applications with 3-state output capability. This component operates across a supply voltage range of 1.2V to 3.6V and is rated for operating temperatures from -40°C to 125°C. The device is currently in active production status and is RoHS3 compliant with MSL Level 1 (unlimited moisture sensitivity).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific packaging and qualification needs while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC245APW/AUJ are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Logic type and function (Transceiver, Non-Inverting)
• Bit width and element count (1 Element, 8 Bits per Element)
• Output configuration (3-State)
• Output current capability (24mA High, 24mA Low)
• Supply voltage range (1.2V ~ 3.6V)
• Operating temperature range (-40°C ~ 125°C)
• Package type and physical dimensions (20-TSSOP)
• Surface mount compatibility
• Compliance certifications (RoHS3, MSL Level 1)

All identified substitutes maintain identical performance across these parameters. Variations in packaging format (Bulk vs. Tape & Reel), manufacturer designation, and automotive qualification (AEC-Q100) represent the primary differentiators among equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed maintain full parametric equivalence for standard industrial applications. Selection among these substitutes should be based on the following criteria:

74LVC245APW,118: Recommended for high-volume procurement due to superior inventory availability (190,454 units). Bulk packaging format is suitable for manufacturing environments with established component handling procedures. Maintains identical electrical specifications and RoHS3 compliance.

74LVC245APW-Q100J: Required for automotive applications requiring AEC-Q100 qualification. Supplied in Tape & Reel format, appropriate for automated assembly processes. Nexperia USA Inc. manufacturing designation. Inventory availability supports moderate-volume requirements.

74LVCH245APW,118: Highest inventory availability (257,577 units) among all substitutes. Bulk packaging format. Belongs to the 74LVCH series variant. Suitable for applications where extended supply chain security is prioritized.

74LVC245APW/AUJ: Original specification part. Standard packaging format. Lowest inventory position (875 units). Recommended when original manufacturer designation is contractually required or when inventory constraints do not apply.

All parts are compliant with RoHS3 and REACH regulations. MSL Level 1 rating indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can 74LVCH245APW,118 be used as a direct replacement for 74LVC245APW/AUJ?

A: Yes. Both parts maintain identical electrical specifications across all critical parameters: 8-bit non-inverting transceiver function, 3-state output, 24mA output current, 1.2V to 3.6V supply voltage range, and -40°C to 125°C operating temperature. The primary difference is series designation (74LVCH vs. 74LVC) and packaging format (Bulk). Functional compatibility is complete.

Q: What is the significance of the AEC-Q100 qualification on 74LVC245APW-Q100J?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and testing standards. This qualification is required for automotive applications but is not necessary for industrial or consumer electronics. Standard-grade parts (74LVC245APW,118 and 74LVCH245APW,118) are suitable for non-automotive applications.

Q: Are there differences in pin configuration between these substitutes?

A: No. All parts use the 20-TSSOP package with identical pin assignments and physical dimensions (0.173" width, 4.40mm). PCB footprints are interchangeable without modification.

Q: How does packaging format (Bulk vs. Tape & Reel) affect part selection?

A: Packaging format affects handling and assembly processes but not electrical performance. Tape & Reel format (74LVC245APW-Q100J) is optimized for automated pick-and-place assembly. Bulk format (74LVC245APW,118 and 74LVCH245APW,118) is suitable for manual assembly or environments with established bulk component handling procedures.

Q: What is the difference between NXP USA Inc., NXP Semiconductors, and Nexperia USA Inc. designations?

A: These represent different manufacturing entities within the NXP/Nexperia corporate structure. All maintain equivalent quality standards and compliance certifications. Parts are functionally and electrically identical regardless of manufacturer designation.

Q: Is MSL Level 1 rating important for component storage?

A: MSL Level 1 indicates unlimited shelf life under standard storage conditions (typically 30°C, 85% relative humidity). No special moisture control or baking procedures are required before assembly, simplifying inventory management and reducing component handling costs.
