74ALVC245WM Equivalent & Substitute Parts

Part Overview

The 74ALVC245WM is a non-inverting transceiver logic IC manufactured by onsemi, designed for 8-bit bidirectional data transfer with 3-state output capability. Operating across a supply voltage range of 1.65V to 3.6V, this component is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVC245WM is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.65V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 20-SOIC (0.295", 7.50mm Width)

Substitution Categories:

Direct Manufacturer Equivalents maintain identical electrical specifications and package dimensions. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Equivalents share all critical electrical parameters but may differ in package width or series designation (74ALVC vs. 74ALVCH). These require mechanical verification for PCB footprint compatibility.

Parametric Equivalents match all electrical specifications and primary package type but differ in packaging format (Tube vs. Tape & Reel). These are electrically and mechanically compatible but may require supply chain adjustment.

Engineering Selection Recommendations

Primary Recommendation: SN74ALVC245DWR (Texas Instruments)

The SN74ALVC245DWR is the optimal substitute for the obsolete 74ALVC245WM. This part maintains identical electrical specifications, package dimensions (20-SOIC 0.295" width), and operating parameters. The component carries Active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance and REACH unaffected status satisfy modern regulatory requirements. Packaging in Tape & Reel format supports automated assembly processes.

Secondary Recommendation: SN74ALVC245DW (Texas Instruments)

The SN74ALVC245DW provides parametric equivalence with identical electrical and mechanical specifications. This variant is supplied in Tube packaging, suitable for lower-volume applications or manual assembly workflows. Active product status and full compliance certifications apply.

Alternative Consideration: 74ALVC245D,118 (NXP USA Inc.)

The 74ALVC245D,118 from NXP maintains all critical electrical parameters and package dimensions. This part is available in Bulk packaging and carries Active product status. Selection of this alternative depends on supply chain preferences and packaging requirements for your manufacturing process.

Package Width Consideration: SN74ALVC245NSR (Texas Instruments)

The SN74ALVC245NSR differs in package width (0.209" vs. 0.295"), resulting in a narrower 20-SO footprint. This part is electrically equivalent but requires PCB footprint verification before implementation. Use only if your design accommodates the reduced package width.

Series Variant Consideration: SN74ALVCH245DWR and SN74ALVCH245DW (Texas Instruments)

The 74ALVCH series variants (SN74ALVCH245DWR and SN74ALVCH245DW) maintain all electrical specifications and package dimensions of the original part. These represent a series upgrade within the same functional family. Selection depends on design requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74ALVC245WM with any of the listed substitutes?

A: Yes, all listed substitutes maintain identical electrical specifications (1.65V ~ 3.6V supply, 24mA output current, -40°C ~ 85°C operating range) and the same 8-bit non-inverting transceiver functionality. However, verify package width compatibility for parts with different case dimensions (SN74ALVC245NSR uses 0.209" width vs. standard 0.295").

Q: What is the difference between 74ALVC and 74ALVCH series?

A: Both series share identical electrical parameters and package dimensions specified in this reference. The 74ALVCH represents a series variant within the same functional family. Selection between series depends on design requirements and supply chain availability.

Q: Are there any compliance or regulatory differences between substitutes?

A: All active substitute parts carry RoHS3 compliance and REACH unaffected status. The original 74ALVC245WM (obsolete) does not carry these certifications. Modern designs should prioritize active parts with current compliance documentation.

Q: What packaging formats are available?

A: Substitutes are available in three packaging formats: Tape & Reel (TR) for automated assembly, Tube for manual assembly or lower volumes, and Bulk for specific supply chain requirements. All maintain identical electrical and mechanical specifications within their respective formats.

Q: Does package width affect PCB compatibility?

A: Yes. The SN74ALVC245NSR uses a narrower 20-SO package (0.209" width) compared to the standard 20-SOIC (0.295" width) used by the original part and most substitutes. Verify your PCB footprint before selecting this variant.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special handling or storage conditions. All listed substitutes with specified MSL carry this rating.

Q: Are all substitutes in active production?

A: Yes. All listed substitutes carry Active product status, ensuring continued availability and supply chain stability. The original 74ALVC245WM is obsolete and should be replaced in new designs.
