SN74LVC245APWRG3 Equivalent & Substitute Parts

Part Overview

The SN74LVC245APWRG3 is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments. This 8-bit, 1-element transceiver features 3-state output capability and operates across a supply voltage range of 1.65V to 3.6V. The device is housed in a 20-TSSOP surface mount package and is classified as an active product with full RoHS3 compliance. Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when equivalent functionality from alternative manufacturers is preferred for supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC245APWRG3 is determined by strict adherence to the following critical parameters: logic type (transceiver, non-inverting), number of elements (1), bits per element (8), output type (3-state), output current capability (24mA minimum for both high and low), package type (20-TSSOP), and surface mount mounting type. Supply voltage range and operating temperature range define the operational envelope within which substitutes must function. Parts are grouped into three categories: parametric equivalents from Texas Instruments with identical electrical specifications but different packaging formats; manufacturer-recommended equivalents from alternative suppliers (onsemi, NXP Semiconductors, Diodes Incorporated) that maintain core functionality; and parts with extended voltage or temperature ranges that provide additional operational flexibility while maintaining base compatibility.

Engineering Selection Recommendations

Texas Instruments 74LVC series parts (SN74LVC245APWR, SN74LVC245APWT) are direct parametric equivalents with identical electrical specifications and full active product status. Selection between these parts depends solely on packaging format requirements: Cut Tape & Digi-Reel® format for automated pick-and-place operations, or Tape & Reel format for standard reel-based assembly lines.

Texas Instruments 74LVCH series parts (SN74LVCH245APWR, SN74LVCH245APWT) maintain identical electrical performance and active status, with packaging format as the only differentiator.

NXP Semiconductors 74LVC245APW,118 provides the widest supply voltage range (1.2V to 3.6V) while maintaining active product status and identical operating temperature range. This part is suitable for applications requiring extended low-voltage operation.

onsemi 74LCX245 series parts (74LCX245MTCX, MC74LCX245DTG, MC74LCX245DTR2G) operate within a narrower minimum supply voltage (2V minimum) but extend the maximum supply voltage to 5.5V and operating temperature range to -55°C to 125°C. These parts are appropriate for applications requiring extended temperature or voltage ranges. MC74LCX245DTR2G in Tape & Reel format is preferred over MC74LCX245DTG in Tube format for high-volume manufacturing.

Diodes Incorporated 74LVC245AT20-13 provides parametric equivalence with identical electrical specifications and active status. Moisture sensitivity level is rated at MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the primary part, requiring consideration of storage and handling protocols.

NLV74LCX245DTR2G from onsemi is classified as obsolete and should not be selected for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can I substitute SN74LVC245APWR for SN74LVC245APWRG3?

A: Yes. Both parts are Texas Instruments 74LVC series with identical electrical specifications (1.65V to 3.6V supply, -40°C to 125°C operating range, 24mA output current). The difference is packaging format: SN74LVC245APWR uses Cut Tape & Digi-Reel® format while SN74LVC245APWRG3 uses Tape & Reel format. Verify your assembly equipment compatibility with the packaging format before substitution.

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

A: Both series provide identical logic functionality (non-inverting transceiver, 8-bit, 3-state output). The 74LCX series from onsemi operates with a minimum supply voltage of 2V (versus 1.65V for 74LVC) and extends the maximum supply voltage to 5.5V (versus 3.6V for 74LVC). Operating temperature range extends to -55°C for 74LCX. Select 74LCX only if your application requires these extended ranges.

Q: Is the NXP 74LVC245APW,118 compatible with my design?

A: Yes, if your application operates within the 1.2V to 3.6V supply range and -40°C to 125°C temperature range. The NXP part provides the lowest minimum supply voltage (1.2V) among all listed substitutes, making it suitable for low-power applications. All other electrical parameters match the primary part.

Q: Why is NLV74LCX245DTR2G listed as obsolete?

A: NLV74LCX245DTR2G is marked as obsolete product status and should not be selected for new designs. Use active alternatives such as MC74LCX245DTR2G from onsemi instead.

Q: Does moisture sensitivity level affect my component selection?

A: Moisture sensitivity level (MSL) determines storage and handling requirements. The primary part SN74LVC245APWRG3 has MSL 1 (Unlimited), allowing indefinite storage without baking. Diodes Incorporated 74LVC245AT20-13 has MSL 3 (168 Hours), requiring baking before reflow if storage exceeds 168 hours in standard humidity conditions. Verify your supply chain and storage capabilities before selecting MSL 3 parts.

Q: Can I use different packaging formats interchangeably?

A: No. Packaging format (Tape & Reel, Cut Tape & Digi-Reel®, Tube) is determined by your assembly equipment and manufacturing process. Verify your equipment specifications before substituting parts with different packaging formats. All listed parts use identical 20-TSSOP case dimensions, ensuring PCB footprint compatibility.
