Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74VHC04N is determined by the following critical parameters:

• Logic Function: Both parts must provide 6-channel inverter functionality with single input per channel
• Electrical Specifications: Supply voltage range, quiescent current, output current, and propagation delay must be equivalent or superior
• Package Compatibility: Physical package must be 14-DIP format to ensure direct board-level compatibility
• Mounting Type: Through-hole mounting requirement must be maintained
• Input/Output Logic Levels: Threshold voltages must support the same signal integrity requirements

The SN74AHC04N from Texas Instruments meets all substitution criteria as an active product with identical functional specifications and package format.

Parameter Comparison

Engineering Selection Recommendations

The SN74AHC04N is a direct functional equivalent to the 74VHC04N. Both components share identical electrical performance specifications and physical packaging. The SN74AHC04N offers the advantage of active product status with ROHS3 compliance certification, making it suitable for new designs and legacy system replacements.

The extended operating temperature range of the SN74AHC04N (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin for applications operating at elevated ambient conditions. Pin-for-pin compatibility and matching propagation delay characteristics ensure direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the SN74AHC04N directly replace the 74VHC04N on existing PCBs?

A: Yes. Both components use identical 14-DIP through-hole packaging with matching pin assignments. No board modifications are required for substitution.

Q: Are the electrical specifications identical between these parts?

A: The core electrical specifications are equivalent: supply voltage range (2V to 5.5V), quiescent current (2 µA max), output current (8mA), and propagation delay (7.5ns @ 5V, 50pF) are identical. The SN74AHC04N provides an extended operating temperature range to 125°C.

Q: What is the significance of the product status difference?

A: The 74VHC04N is obsolete, meaning onsemi no longer manufactures or supports this component. The SN74AHC04N is active and available from Texas Instruments, ensuring long-term supply chain availability and technical support.

Q: Does the SN74AHC04N meet current regulatory requirements?

A: Yes. The SN74AHC04N is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Are there any input or output logic level differences?

A: The SN74AHC04N specifies input logic level ranges (Low: 0.5V ~ 1.65V, High: 1.5V ~ 3.85V) while the 74VHC04N provides fixed thresholds (Low: 0.5V, High: 1.5V). Both specifications are compatible with standard TTL/CMOS logic signal levels.
