SN74ACT04PWRG4 Equivalent & Substitute Parts

Part Overview

The SN74ACT04PWRG4 is a 6-channel inverter logic IC manufactured by Texas Instruments 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 device performs standard logic inversion across six independent channels with TTL-compatible input and output levels, operating within the 4.5V to 5.5V supply voltage range.

Substitute Part Grouping Explanation

Substitution for the SN74ACT04PWRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 24mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ 5V, 50pF: 8.5ns
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

All identified substitute parts maintain these electrical and mechanical specifications, ensuring functional and physical compatibility. Differences in quiescent current (2µA vs. 4µA) and product status do not affect substitution eligibility within this logic category.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT04PWR is the primary substitute, maintaining active product status from the original manufacturer (Texas Instruments) with identical electrical specifications and lower quiescent current matching the main part. This option provides continuity with the original design source.

74ACT04MTCX and MC74ACT04DTR2G are functionally equivalent alternatives from onsemi, both with active product status. These parts exhibit slightly elevated quiescent current (4µA vs. 2µA) but maintain all critical electrical parameters and timing specifications. Both are available in Tape & Reel packaging for production environments.

All substitute parts carry ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory requirements of the main part.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT04PWR directly replace SN74ACT04PWRG4 in existing designs?

A: Yes. SN74ACT04PWR maintains identical electrical specifications, operating temperature range, and 14-TSSOP package dimensions. The primary difference is product status (active vs. obsolete) and packaging format availability.

Q: What is the significance of the quiescent current difference between the main part and onsemi substitutes?

A: The main part specifies 2µA maximum quiescent current, while 74ACT04MTCX and MC74ACT04DTR2G specify 4µA. This difference does not affect functional compatibility or logic operation. Selection depends on power consumption requirements for the specific application.

Q: Are all substitute parts available in the same 14-TSSOP package?

A: Yes. All substitute parts use the 14-TSSOP (0.173", 4.40mm Width) package with surface mount technology, ensuring physical compatibility with existing PCB layouts.

Q: Do packaging format differences (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format differences relate only to procurement and handling methods. Electrical and functional performance remains identical regardless of packaging option selected.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance and MSL Level 1 rating, matching the regulatory and environmental specifications of the main part.
