Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74VHCT04ASJX are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical logic type (inverter), circuit count (6 channels), input count (1), supply voltage range (4.5V ~ 5.5V), quiescent current (2 µA max), output current (8mA high/low), input logic levels (0.8V low, 2V high), and propagation delay (7.7ns @ 5V, 50pF).

Mechanical Compatibility: All substitute parts use surface mount technology with 14-pin SOIC packaging and MSL rating of 1 (Unlimited).

Regulatory Compliance: All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification.

The primary distinction among substitute parts is product status and operating temperature range. Active status parts with extended temperature ranges (-40°C ~ 125°C) provide superior availability and design longevity compared to the obsolete 74VHCT04ASJX.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74AHCT04DR (Texas Instruments)

The SN74AHCT04DR is the preferred substitute for the 74VHCT04ASJX. This part maintains active product status with extended operating temperature range (-40°C ~ 125°C), ROHS3 compliance, and the highest inventory availability (21,300 pcs). The SN74AHCT04DR is supplied in Cut Tape and Digi-Reel packaging, supporting both prototype and production volume requirements.

Secondary Recommendation: SN74AHCT04NSR (Texas Instruments)

The SN74AHCT04NSR provides an alternative from Texas Instruments with active product status and extended temperature range. This part is available in Cut Tape and Digi-Reel packaging with 6,100 pcs in stock.

Alternative Option: 74AHCT04D,118 (Nexperia USA Inc.)

The 74AHCT04D,118 from Nexperia maintains active product status and extended operating temperature range. This part is supplied in Tape & Reel packaging with 744 pcs available. Note that the package width differs (0.154" vs. 0.209"), requiring PCB layout verification.

Not Recommended: SN74AHCT04D (Texas Instruments)

The SN74AHCT04D is discontinued at DiGi Electronics and should not be selected for new designs despite maintaining electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74VHCT04ASJX with any of the substitute parts?

A: All listed substitute parts are electrically and mechanically compatible with the 74VHCT04ASJX. They maintain identical logic functionality, supply voltage range, output current, propagation delay, and input logic levels. However, verify PCB layout compatibility with the package width specifications before implementation.

Q: What is the difference between the 74VHCT and 74AHCT series?

A: Both series are 6-channel inverter logic ICs with identical electrical specifications within the provided parameters. The primary difference is manufacturer and product status. The 74VHCT04ASJX is obsolete, while the 74AHCT variants are active or recently discontinued, providing better long-term availability.

Q: Does the operating temperature range difference affect compatibility?

A: The 74VHCT04ASJX operates from -40°C to 85°C, while substitute parts operate from -40°C to 125°C. All substitute parts maintain the same electrical performance within the 74VHCT04ASJX temperature range. The extended range in substitute parts provides additional design margin for high-temperature applications.

Q: Are there package width differences I should consider?

A: The 74VHCT04ASJX uses a 14-SOIC package with 0.209" width. The SN74AHCT04NSR maintains this width. The 74AHCT04D,118, SN74AHCT04D, and SN74AHCT04DR use 14-SOIC packages with 0.154" width. Verify PCB footprint compatibility before design implementation.

Q: Which substitute part has the best availability?

A: The SN74AHCT04DR has the highest inventory with 21,300 pcs in stock, followed by SN74AHCT04NSR with 6,100 pcs and 74AHCT04D,118 with 744 pcs.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are ROHS3 compliant. The 74VHCT04ASJX RoHS status is not specified in the provided data.
