SN74LVC245ADWR Equivalent & Substitute Parts

Part Overview

The SN74LVC245ADWR is a non-inverting transceiver logic IC manufactured by Texas Instruments, designed for 8-bit data bus applications with 3-state output capability. Operating across a supply voltage range of 1.65V to 3.6V, this component is housed in a 20-SOIC surface mount package and is classified as Active product status. Substitute parts are necessary when primary inventory is unavailable, when alternative packaging formats are required, or when extended operating temperature ranges or different supply voltage specifications are needed for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC245ADWR is determined by the following critical parameters:

Primary Substitution Criteria:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• Current - Output High, Low: 24mA minimum (or equivalent)
• Voltage - Supply: Must encompass or overlap with 1.65V ~ 3.6V range
• Operating Temperature: Must support -40°C ~ 125°C minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 or MSL 3 acceptable

Substitute parts are grouped based on exact functional equivalence in core logic parameters and package specifications. Variations in supply voltage range, output current ratings, and temperature operating ranges are noted as they may affect application suitability.

Parameter Comparison

Engineering Selection Recommendations

SN74LVCH245ADWR (Texas Instruments): Parametric equivalent with identical electrical specifications and supply voltage range. Maintains MSL 1 moisture sensitivity rating. Suitable for direct substitution in applications requiring Texas Instruments sourcing or when inventory of the primary part is unavailable.

74LVC245AD,118 (Nexperia USA Inc.): Functionally equivalent with extended lower supply voltage limit (1.2V minimum). Maintains 24mA output current and full temperature range support. Available in Cut Tape packaging. Suitable for applications with lower voltage requirements or when Nexperia sourcing is preferred.

74LVCH245AD,118 (Nexperia USA Inc.): Functionally equivalent with extended lower supply voltage limit (1.2V minimum). Available in Tape & Reel packaging format. Suitable for high-volume production environments or when alternative packaging is required.

MC74LCX245DWR2G (onsemi): Functionally equivalent with extended supply voltage range (2V ~ 5.5V) and extended operating temperature range (-55°C ~ 125°C). MSL 3 rating requires controlled storage conditions. Suitable for applications requiring higher supply voltage tolerance or extended low-temperature operation.

All substitute parts maintain Active product status and ROHS3 compliance. Selection should be based on specific application voltage requirements, packaging format availability, and manufacturer sourcing preferences.

Frequently Asked Questions (FAQ)

Q: Can SN74LVCH245ADWR replace SN74LVC245ADWR directly?

A: Yes. Both parts share identical electrical specifications, supply voltage range (1.65V ~ 3.6V), output current ratings (24mA), operating temperature range (-40°C ~ 125°C), and 20-SOIC package format. Both maintain MSL 1 moisture sensitivity rating.

Q: What is the difference between the Nexperia 74LVC245AD,118 and 74LVCH245AD,118 variants?

A: Both Nexperia parts are functionally equivalent to the main part. The primary difference is packaging format: 74LVC245AD,118 is supplied in Cut Tape format, while 74LVCH245AD,118 is supplied in Tape & Reel format. Electrical specifications and supply voltage range (1.2V ~ 3.6V) are identical.

Q: Can MC74LCX245DWR2G be used in applications designed for SN74LVC245ADWR?

A: MC74LCX245DWR2G is functionally equivalent but has different electrical specifications. It supports a higher supply voltage range (2V ~ 5.5V) and extended operating temperature range (-55°C ~ 125°C). It carries MSL 3 rating instead of MSL 1. Substitution is valid for applications within the overlapping voltage range (2V ~ 3.6V) and temperature range (-40°C ~ 125°C), provided MSL 3 storage requirements are met.

Q: What does MSL 1 versus MSL 3 mean for component handling?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage. MSL 3 (168 Hours) requires the component to be used within 168 hours of package opening or stored in controlled humidity conditions. This affects supply chain logistics and inventory management.

Q: Are all substitute parts available in 20-SOIC package?

A: Yes. All listed substitute parts are housed in 20-SOIC (0.295", 7.50mm Width) surface mount packages, ensuring mechanical and electrical compatibility with the original SN74LVC245ADWR footprint.

Q: Which substitute part has the widest operating temperature range?

A: MC74LCX245DWR2G supports -55°C ~ 125°C, extending the lower temperature limit by 15°C compared to the main part and other substitutes, which operate from -40°C ~ 125°C.
