Substitute Part Grouping Explanation

Substitution for the 74LCX07MX is determined by the following critical parameters:

Logic Type: Buffer, Non-Inverting
Number of Elements: 6
Number of Bits per Element: 1
Output Type: Open Drain
Package / Case: 14-SOIC (0.154", 3.90mm Width)
Current - Output Low: 24mA or 32mA
Voltage - Supply: Minimum 2V compatibility required

Substitute parts are grouped into two categories:

Direct Substitutes (onsemi 74LCX series): Parts maintaining identical electrical specifications and packaging from the same manufacturer series, differing only in packaging format (Cut Tape vs. Tape & Reel vs. Tube).

Cross-Manufacturer Substitutes (74LVC series): Parts from alternative manufacturers (Texas Instruments, Diodes Incorporated, Nexperia) with compatible logic function, element count, output type, and package, but with enhanced specifications including extended voltage supply range (1.2V to 1.65V minimum) and extended operating temperature range (-40°C to 125°C).

Engineering Selection Recommendations

For Direct Replacement (onsemi 74LCX series):

MC74LCX07DR2G and MC74LCX07DG are active production alternatives from onsemi maintaining the 74LCX base product number. Both parts preserve the original 2V to 5.5V supply voltage range and -40°C to 85°C operating temperature specification. Output current is reduced to 24mA versus the original 32mA specification. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating. MC74LCX07DR2G is supplied in Tape & Reel format, while MC74LCX07DG is supplied in Tube format.

For Enhanced Specification Replacement (74LVC series):

Cross-manufacturer 74LVC07 variants from Texas Instruments, Diodes Incorporated, and Nexperia provide extended operating specifications. All 74LVC parts support lower minimum supply voltage (1.65V or 1.2V) and extended operating temperature range to 125°C. All substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating and active product status.

Texas Instruments SN74LVC07ADR, SN74LVC07AD, SN74LVC07ADRG3, SN74LVC07ADT, and SN74LVC07ANS all deliver 24mA output current and 1.65V minimum supply voltage. Diodes Incorporated 74LVC07AS14-13 maintains 32mA output current matching the original specification with 1.65V minimum supply voltage. Nexperia 74LVC07AD,118 and 74LVC07AD-Q100J provide 32mA output current with extended 1.2V minimum supply voltage. The 74LVC07AD-Q100J variant includes AEC-Q100 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MC74LCX07DR2G directly replace 74LCX07MX in all applications?

A: MC74LCX07DR2G maintains identical logic function, element count, output type, and package specification. The primary difference is reduced output current (24mA versus 32mA). Applications requiring the full 32mA output current specification must evaluate whether the reduced current meets circuit requirements. Both parts operate across the same 2V to 5.5V supply voltage and -40°C to 85°C temperature range.

Q: What are the advantages of 74LVC07 series substitutes over onsemi 74LCX alternatives?

A: 74LVC07 parts from Texas Instruments, Diodes Incorporated, and Nexperia provide extended operating specifications including lower minimum supply voltage (1.65V or 1.2V versus 2V) and extended operating temperature range to 125°C. All 74LVC variants are in active production status with ROHS3 compliance. These enhanced specifications provide greater design flexibility for applications requiring lower voltage operation or wider temperature ranges.

Q: Are all substitute parts available in the same package?

A: All listed substitute parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package, maintaining mechanical and electrical compatibility with the original 74LCX07MX. Packaging format differs (Cut Tape, Tape & Reel, or Tube) but does not affect circuit-level compatibility.

Q: Which substitute part best matches the original 74LCX07MX electrical specifications?

A: MC74LCX07DR2G and MC74LCX07DG from onsemi most closely match the original specification, maintaining the 2V to 5.5V supply voltage range and -40°C to 85°C operating temperature. The only difference is reduced output current (24mA versus 32mA). For applications requiring the full 32mA specification, Diodes Incorporated 74LVC07AS14-13 or Nexperia 74LVC07AD,118 and 74LVC07AD-Q100J provide 32mA output current with enhanced voltage and temperature specifications.

Q: Is the 74LVC07AD-Q100J suitable for automotive applications?

A: 74LVC07AD-Q100J includes AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. This variant is supplied in Tape & Reel format with ROHS3 compliance and unlimited moisture sensitivity rating.

Q: What is the difference between SN74LVC07ADR, SN74LVC07AD, SN74LVC07ADRG3, SN74LVC07ADT, and SN74LVC07ANS from Texas Instruments?

A: All five Texas Instruments variants maintain identical electrical specifications: 24mA output current, 1.65V to 5.5V supply voltage, and -40°C to 125°C operating temperature. Differences are in packaging format: SN74LVC07ADR is Cut Tape & Digi-Reel, SN74LVC07AD is Tube, SN74LVC07ADRG3 is Tape & Reel, SN74LVC07ADT is Tape & Reel, and SN74LVC07ANS is prototype format. Selection depends on procurement and assembly requirements.
