Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC04ADTR2G is determined by the following critical parameters:

• Logic Function: Both parts must be 6-channel inverters with single input configuration
• Package Compatibility: Identical 14-TSSOP surface mount package required for PCB layout compatibility
• Electrical Characteristics: Supply voltage range, output current capability, and propagation delay must meet or exceed application requirements
• Environmental Compliance: RoHS3 compliance and MSL rating must be maintained
• Product Status: Active status of substitute parts ensures long-term availability

The MC74LCX04DTR2G qualifies as a direct substitute based on matching logic function, package type, and compliance certifications. The 74LCX series represents an enhanced variant of the 74LVC architecture with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MC74LCX04DTR2G is suitable as a substitute for the obsolete 74LVC04ADTR2G based on the following factors:

• Functional Equivalence: Both devices provide identical 6-channel inverter logic with matching pin configuration and 14-TSSOP package footprint
• Active Product Status: The MC74LCX04DTR2G maintains active production status, ensuring component availability for current and future production runs
• Compliance Certification: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory and environmental requirements
• Performance Enhancement: The 74LCX variant demonstrates improved quiescent current (10 µA vs. 40 µA) and faster propagation delay (5.2ns vs. 6ns), providing performance benefits without design modification
• Supply Voltage Consideration: The substitute operates within a 2V to 3.6V range, which is compatible with applications using 3.3V or higher supply voltages. Applications requiring operation below 2V must retain the original 74LVC04ADTR2G or identify alternative solutions

Frequently Asked Questions (FAQ)

Q: Can the MC74LCX04DTR2G be used as a direct pin-for-pin replacement?

A: Yes. Both devices share identical pin configuration, logic function, and 14-TSSOP package dimensions. No PCB layout modifications are required for substitution.

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

A: The 74LCX series represents an enhanced variant with improved electrical characteristics, including lower quiescent current consumption and faster propagation delay. The 74LCX minimum supply voltage is 2V, compared to 1.2V for the 74LVC series.

Q: Is the substitute part suitable for low-voltage applications below 2V?

A: No. Applications requiring operation below 2V supply voltage must use the original 74LVC04ADTR2G or identify alternative components rated for the required voltage range. The MC74LCX04DTR2G minimum supply voltage is 2V.

Q: Are there any thermal or environmental differences between these parts?

A: The MC74LCX04DTR2G supports an extended lower operating temperature limit of -55°C compared to -40°C for the 74LVC04ADTR2G. Both parts maintain identical upper temperature limits and MSL ratings.

Q: What packaging options are available for the substitute part?

A: The MC74LCX04DTR2G is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original 74LVC04ADTR2G packaging format is not specified in the provided data.
