Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74HC14DRG4 is determined by strict equivalence across the following critical parameters:

Core Functional Requirements:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Features: Schmitt Trigger
• Voltage - Supply: 2V ~ 6V
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Electrical Performance Boundaries:

• Current - Quiescent (Max): ≤ 2 µA
• Current - Output High, Low: 5.2mA, 5.2mA
• Input Logic Level - Low: 0.3V ~ 1.2V
• Input Logic Level - High: 1.5V ~ 4.2V
• Max Propagation Delay @ 6V, 50pF: ≤ 21ns

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into three categories based on their relationship to the main part: Parametric Equivalents (identical electrical specifications and packaging), Direct Manufacturers (alternative sources with equivalent or superior performance), and Upgrades (enhanced temperature range or performance characteristics).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement): SN74HC14DR and SN74HC14DRG3 are parametric equivalents from Texas Instruments with identical electrical specifications to the SN74HC14DRG4. Both are active products and suitable for direct substitution. SN74HC14DR is available in Cut Tape & Digi-Reel packaging, while SN74HC14DRG3 is supplied in Tape & Reel format.

Direct Manufacturer Alternatives: MC74HC14ADR2G (onsemi) and MC74HC14ADG (onsemi) offer superior performance with reduced quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 21ns). Both support extended operating temperature range (-55°C ~ 125°C). These parts are active and ROHS3 compliant.

Extended Temperature Range Options: 74HC14D,653 (Nexperia), MM74HC14M, and MM74HC14MX (onsemi) extend the upper operating temperature to 125°C while maintaining electrical equivalence. These are suitable for applications requiring broader thermal performance.

Automotive-Grade Alternative: M74HC14YRM13TR (STMicroelectronics) is AEC-Q100 qualified and suitable for automotive applications requiring functional equivalence with extended temperature support (-40°C ~ 125°C).

Note on 74HC14S14-13: Diodes Incorporated's 74HC14S14-13 has elevated quiescent current (20 µA maximum) compared to the 2 µA specification of the main part. This part is suitable only for applications where quiescent current is not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC14DR as a direct replacement for SN74HC14DRG4? A: Yes. SN74HC14DR is a parametric equivalent with identical electrical specifications, operating temperature range, and 14-SOIC packaging. The difference is packaging format (Cut Tape & Digi-Reel vs. Digi-Reel).

Q: What is the difference between the onsemi MC74HC14ADR2G and the Texas Instruments SN74HC14DRG4? A: MC74HC14ADR2G offers improved performance with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 21ns). It also supports a wider operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C). All other electrical parameters remain equivalent.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and have MSL rating of 1 (Unlimited), matching the compliance profile of the main part.

Q: Can I use MM74HC14M or MM74HC14MX in place of the SN74HC14DRG4? A: Yes. Both onsemi parts are parametric equivalents with identical electrical specifications and extended operating temperature range (-55°C ~ 125°C). The primary difference is packaging format: MM74HC14M is supplied in Tube, while MM74HC14MX is available in Cut Tape & Digi-Reel.

Q: Why does 74HC14S14-13 have higher quiescent current? A: The Diodes Incorporated 74HC14S14-13 specifies a maximum quiescent current of 20 µA, which exceeds the 2 µA specification of the main part. This part is suitable only for applications where quiescent current specifications are not critical to system performance.

Q: What packaging options are available for substitutes? A: Substitute parts are available in multiple packaging formats: Cut Tape & Digi-Reel (SN74HC14DR, MC74HC14ADR2G, 74HC14D,653, MM74HC14MX, M74HC14YRM13TR), Tape & Reel (SN74HC14DRG3, SN74HC14DT, 74HC14S14-13), and Tube (MM74HC14M, MC74HC14ADG). Select based on your procurement and assembly requirements.

Q: Is M74HC14YRM13TR suitable for automotive applications? A: Yes. M74HC14YRM13TR is AEC-Q100 qualified and carries automotive-grade designation, making it suitable for automotive applications requiring functional equivalence with extended temperature support.
