74ACT04MTC Equivalent & Substitute Parts

Part Overview

The 74ACT04MTC is a 6-channel inverter logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74ACT04 series provides standard inverter functionality across the 74ACT logic family, with multiple manufacturers offering compatible alternatives in different packaging and delivery formats.

Substitute Part Grouping Explanation

Substitution of the 74ACT04MTC is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter (6 channels, 1 input per channel)
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 24mA, propagation delay 8.5ns @ 5V/50pF
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Base Product Number: 74ACT04

Substitute parts are grouped into three categories based on packaging and delivery format:

Direct Manufacturer Equivalent (Same Package): MC74ACT04DTR2G (onsemi, 14-TSSOP, Tape & Reel)

Similar Manufacturer Alternatives (Package Variant): SN74ACT04DBR (Texas Instruments, 14-SSOP, Tape & Reel)

Parametric Equivalents (Same Package, Different Delivery): SN74ACT04PWR (Texas Instruments, 14-TSSOP, Cut Tape & Digi-Reel®), SN74ACT04PW (Texas Instruments, 14-TSSOP, Tube)

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MC74ACT04DTR2G (onsemi) is the direct equivalent replacement for 74ACT04MTC. Both parts are manufactured by onsemi, share identical electrical specifications and package dimensions (14-TSSOP), and maintain active product status. This part is available in Tape & Reel format with 12,553 units in stock.

Secondary Recommendations: SN74ACT04PWR and SN74ACT04PW (Texas Instruments) are parametric equivalents with identical package footprint (14-TSSOP) and electrical performance. Both are ROHS3 compliant and meet all functional requirements. SN74ACT04PWR is available in Cut Tape & Digi-Reel® format; SN74ACT04PW is supplied in Tube format but is discontinued at DiGi Electronics.

Package Variant Alternative: SN74ACT04DBR (Texas Instruments) is functionally equivalent but uses a 14-SSOP package (0.209" width) instead of 14-TSSOP (0.173" width). This part requires PCB layout modification and is suitable only when package footprint change is acceptable.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical logic functionality. Selection should prioritize availability, packaging format requirements, and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can I use MC74ACT04DTR2G as a direct replacement for 74ACT04MTC?

A: Yes. MC74ACT04DTR2G is a direct equivalent. Both parts share identical electrical specifications, package dimensions (14-TSSOP), and logic functionality. The primary difference is product status (MC74ACT04DTR2G is active) and packaging format (Tape & Reel vs. unspecified for the obsolete part).

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

A: 14-TSSOP has a width of 0.173" (4.40mm), while 14-SSOP has a width of 0.209" (5.30mm). These are different footprints and require separate PCB layouts. Parts in 14-SSOP packages cannot be used as drop-in replacements without PCB modification.

Q: Are Texas Instruments parts (SN74ACT04) compatible with onsemi parts (74ACT04)?

A: Yes, from an electrical and functional standpoint. Both manufacturers produce 74ACT04 inverter ICs with identical logic specifications, supply voltage ranges, output currents, and propagation delays. Package format and delivery method may differ.

Q: Why do some substitute parts show lower quiescent current (2 µA vs. 4 µA)?

A: Lower quiescent current represents improved power efficiency in newer manufacturing processes. This is a beneficial characteristic and does not affect functional compatibility. Parts with 2 µA quiescent current will perform identically to the original 4 µA specification.

Q: Is SN74ACT04PW still available for new designs?

A: SN74ACT04PW is discontinued at DiGi Electronics. While 2,200 units are currently in stock, this part should not be selected for new designs requiring long-term availability. Use SN74ACT04PWR or MC74ACT04DTR2G instead.

Q: What packaging format should I choose for production?

A: Tape & Reel (TR) format is standard for automated assembly. MC74ACT04DTR2G and SN74ACT04DBR are supplied in Tape & Reel. Cut Tape & Digi-Reel® (SN74ACT04PWR) is suitable for mixed-volume production. Tube format (SN74ACT04PW) is typically used for lower-volume or manual assembly applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (MC74ACT04DTR2G, SN74ACT04DBR, SN74ACT04PWR, SN74ACT04PW) are ROHS3 compliant with MSL Level 1 rating, matching the original 74ACT04MTC specifications.
