MM74HC04MTC Equivalent & Substitute Parts

Part Overview

The MM74HC04MTC is a 6-channel inverter logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements. The MM74HC04MTC operates across a 2V to 6V supply voltage range and is suitable for general-purpose logic inversion applications in digital circuits.

Substitute Part Grouping Explanation

Substitute parts for the MM74HC04MTC are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 2V ~ 6V
• Current - Output High, Low: 5.2mA, 5.2mA
• Input Logic Level - Low: 0.5V ~ 1.8V
• Input Logic Level - High: 1.5V ~ 4.2V
• Mounting Type: Surface Mount
• Base Product Number: 74HC04
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Grouping Categories:

Direct Equivalents (Identical Package): Parts with 14-TSSOP package matching the original specification.

Similar Equivalents (Alternative Package): Parts with 14-SSOP package, which differs in physical dimensions but maintains electrical compatibility.

Active vs. Obsolete Status: Substitute parts are available in both active production status and discontinued status, allowing selection based on supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs:

Select MC74HC04ADTR2G (onsemi) or SN74HC04IPWRG4Q1 (Texas Instruments) as primary substitutes. Both parts are in active production status with full availability. MC74HC04ADTR2G offers improved quiescent current performance (1 µA vs. 2 µA) and extended operating temperature range (-55°C ~ 125°C). SN74HC04IPWRG4Q1 includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components.

For Standard Commercial Applications:

SN74HC04PWR (Texas Instruments) provides active production status with standard commercial specifications matching the original MM74HC04MTC electrical parameters. This part is available in Cut Tape and Digi-Reel packaging.

For Package-Constrained Designs:

SN74HC04DBR (Texas Instruments) is electrically equivalent but uses a 14-SSOP package (0.209", 5.30mm width) instead of 14-TSSOP. This alternative is suitable only if PCB layout accommodates the larger package footprint.

For Legacy or Inventory Considerations:

SN74HC04PWT and SN74HC04PW are discontinued at DiGi Electronics but may be available through alternative distribution channels. These parts maintain full electrical equivalence to the original specification.

Frequently Asked Questions (FAQ)

Q: Can MC74HC04ADTR2G replace MM74HC04MTC directly?

A: Yes. MC74HC04ADTR2G is electrically equivalent with identical pin configuration and 14-TSSOP package. The lower quiescent current (1 µA vs. 2 µA) and extended temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C) represent improvements over the original specification.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: Both are surface mount packages with 14 pins. The 14-TSSOP (0.173" width) is narrower than the 14-SSOP (0.209" width). PCB layout and component placement must accommodate the specific package footprint. SN74HC04DBR uses the larger 14-SSOP package and requires PCB redesign if substituting into existing layouts designed for 14-TSSOP.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original MM74HC04MTC specifications.

Q: Which substitute offers the best performance?

A: MC74HC04ADTR2G provides the fastest propagation delay (13ns vs. 16ns) and lowest quiescent current (1 µA vs. 2 µA), with extended operating temperature range. SN74HC04IPWRG4Q1 includes AEC-Q100 automotive qualification for applications requiring automotive-grade certification.

Q: Can I use Texas Instruments parts as direct replacements for the onsemi original?

A: Yes. All Texas Instruments 74HC04 variants (SN74HC04IPWRG4Q1, SN74HC04PWR, SN74HC04PWT, SN74HC04DBR, SN74HC04PW) are electrically and functionally equivalent. Pin configuration and electrical parameters are identical across manufacturers for the 74HC04 logic family.

Q: What is the significance of "Discontinued at DiGi Electronics" status?

A: This indicates the part is no longer actively stocked by DiGi Electronics but may remain available through other authorized distributors or inventory channels. For new designs, select parts with "Active" status to ensure long-term supply chain availability.
