Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVCU04AD-Q100J are identified based on the following critical parameters:

• Logic Function: 6-channel inverter with single input per channel
• Package Compatibility: 14-SOIC form factor with identical 0.154" width and 3.90mm dimensions
• Supply Voltage Range: Minimum 1.2V to 3.6V operation capability
• Output Drive Capability: Minimum 18mA output current (high and low)
• Propagation Delay: Maximum 4ns at specified voltage and load conditions
• Surface Mount Technology: Compatible with standard SMT assembly processes
• Compliance: RoHS3 compliant status

The MC74LCXU04DR2G qualifies as a substitute based on functional equivalence within these parameters, despite differences in quiescent current, specific input logic levels, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVCU04AD-Q100J and MC74LCXU04DR2G are active products with RoHS3 compliance and MSL Level 1 ratings. Selection between these parts depends on application-specific requirements:

The 74LVCU04AD-Q100J maintains AEC-Q100 automotive qualification and supports operation down to 1.2V supply voltage with an extended operating temperature range to 125°C. This part is suitable for automotive applications requiring the full specified temperature range.

The MC74LCXU04DR2G operates within a 2V to 3.6V supply range with a maximum operating temperature of 85°C. This substitute provides lower quiescent current consumption and faster propagation delay characteristics. Selection of this part is appropriate for applications where the minimum supply voltage requirement is 2V or higher and the maximum operating temperature does not exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can the MC74LCXU04DR2G replace the 74LVCU04AD-Q100J in all applications?

A: The MC74LCXU04DR2G is functionally equivalent for applications operating within 2V to 3.6V supply voltage and -40°C to 85°C temperature range. Applications requiring 1.2V operation or temperatures above 85°C require the 74LVCU04AD-Q100J.

Q: Are the package dimensions identical between these parts?

A: Both parts use the 14-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints are directly compatible.

Q: What is the difference in output drive capability?

A: The 74LVCU04AD-Q100J provides 24mA output current (high and low). The MC74LCXU04DR2G provides 18mA high and 16mA low output current. Applications requiring maximum output current should verify compatibility with the lower drive capability of the substitute.

Q: Does the MC74LCXU04DR2G meet automotive qualification requirements?

A: The MC74LCXU04DR2G is not listed with AEC-Q100 qualification. Applications requiring automotive-grade qualification must use the 74LVCU04AD-Q100J.

Q: What is the quiescent current difference between these parts?

A: The 74LVCU04AD-Q100J has a maximum quiescent current of 40 µA. The MC74LCXU04DR2G has a maximum quiescent current of 10 µA. The substitute provides lower standby power consumption.
