SN74HC14ANS Equivalent & Substitute Parts

Part Overview

The SN74HC14ANS is a 6-channel inverter IC with Schmitt trigger inputs manufactured by Texas Instruments. This device operates across a 2V to 6V supply voltage range and is housed in a 14-SOIC surface mount package. The part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production continuity. The SN74HC14ANS remains available in limited inventory (823 pieces), but active alternatives ensure long-term component sourcing reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC14ANS is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Logic type (Inverter with Schmitt trigger function)
• Number of circuits (6 channels)
• Supply voltage range (2V ~ 6V)
• Quiescent current specification (2 µA maximum)
• Propagation delay performance (19ns @ 6V, 50pF)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Compatibility Parameters:

• Package type (14-SOIC surface mount)
• Physical dimensions (0.209" width, 5.30mm)

Compliance Parameters:

• RoHS3 compliance status
• ECCN and HTSUS classifications

The SN74HC14ANSR qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in input logic level thresholds and packaging format (Cut Tape & Digi-Reel versus standard packaging) do not affect functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SN74HC14ANSR

The SN74HC14ANSR is the direct functional equivalent for the discontinued SN74HC14ANS. Both parts share identical electrical specifications, including supply voltage range, quiescent current, propagation delay, and operating temperature range. Both are housed in the same 14-SOIC package and maintain ROHS3 compliance.

The SN74HC14ANSR holds active product status with significantly higher inventory availability (4549 pieces in stock versus 823 for the original part). This ensures reliable long-term sourcing for production and design continuity.

The SN74HC14ANSR is supplied in Cut Tape and Digi-Reel packaging formats, which are standard for high-volume manufacturing and automated assembly processes. This packaging format does not affect electrical or mechanical compatibility with applications designed for the SN74HC14ANS.

Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent regulatory and trade compliance.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC14ANSR directly replace the SN74HC14ANS in existing designs?

A: Yes. The SN74HC14ANSR is electrically and mechanically equivalent. Both parts feature 6 inverter channels with Schmitt trigger inputs, identical supply voltage ranges (2V ~ 6V), matching propagation delays (19ns @ 6V, 50pF), and the same 14-SOIC package. No circuit modifications are required.

Q: What is the difference between the SN74HC14ANS and SN74HC14ANSR?

A: The primary differences are product status and packaging format. The SN74HC14ANS is discontinued at DiGi Electronics, while the SN74HC14ANSR maintains active status. The SN74HC14ANSR is supplied in Cut Tape and Digi-Reel packaging, which is standard for automated manufacturing. All electrical and mechanical specifications are identical.

Q: Are there differences in input logic level thresholds between these parts?

A: The input logic level specifications differ between the two parts as provided in the data. However, both parts meet the Schmitt trigger inverter functional requirements and operate within the same 2V ~ 6V supply voltage range. The differences do not affect substitution compatibility in standard applications.

Q: Is the SN74HC14ANSR RoHS compliant?

A: Yes. The SN74HC14ANSR is ROHS3 compliant, matching the compliance status of the original SN74HC14ANS. Both parts meet current environmental and regulatory requirements.

Q: What packaging options are available for the SN74HC14ANSR?

A: The SN74HC14ANSR is supplied in Cut Tape (CT) and Digi-Reel packaging formats. Both formats contain the same 14-SOIC component and are suitable for automated pick-and-place assembly. The packaging format does not affect electrical performance or pin compatibility.

Q: Can I use the SN74HC14ANSR in high-temperature applications?

A: Yes. The SN74HC14ANSR operates across the full temperature range of -40°C to 85°C, identical to the SN74HC14ANS. This range covers standard industrial and commercial applications.
