SN74ACT04PWRE4 Equivalent & Substitute Parts

Part Overview

The SN74ACT04PWRE4 is a 6-channel inverter logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This device implements basic logic inversion functionality with TTL-compatible input and output levels. The main part number is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ACT04PWRE4 is determined by strict equivalence across the following parameters:

• Logic Type: Inverter with 6 channels and 1 input per channel
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 24mA/24mA, input logic levels 0.8V (low) and 2V (high), propagation delay 8.5ns @ 5V with 50pF load
• Package: 14-TSSOP surface mount form factor
• Operating Temperature Range: -40°C ~ 85°C
• Compliance: ROHS3 compliant, MSL Level 1

All listed substitute parts maintain these core electrical and mechanical parameters, ensuring functional and physical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT04PWR is the direct Texas Instruments equivalent with active product status, identical electrical specifications, and the same 14-TSSOP package. This part is the primary recommendation for direct replacement of the obsolete SN74ACT04PWRE4.

74ACT04MTCX and MC74ACT04DTR2G are onsemi-manufactured alternatives with active product status. Both maintain full electrical and mechanical compatibility. The quiescent current specification is 4 µA maximum compared to 2 µA for the Texas Instruments variants; this difference remains within acceptable operating margins for standard logic applications. Both onsemi parts are supplied in Tape & Reel packaging.

All substitute parts carry ROHS3 compliance and MSL Level 1 rating, meeting the same environmental and handling requirements as the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT04PWR be used as a direct replacement for SN74ACT04PWRE4?

A: Yes. SN74ACT04PWR is electrically and mechanically identical to SN74ACT04PWRE4, with the same 14-TSSOP package, supply voltage range, output current ratings, input logic levels, and propagation delay specifications. The primary difference is product status: SN74ACT04PWR is active while SN74ACT04PWRE4 is obsolete.

Q: What is the difference between the Texas Instruments and onsemi substitute parts?

A: The Texas Instruments part (SN74ACT04PWR) specifies a maximum quiescent current of 2 µA. The onsemi parts (74ACT04MTCX and MC74ACT04DTR2G) specify 4 µA maximum. All other electrical parameters—supply voltage, output current, input logic levels, and propagation delay—are identical. The quiescent current difference does not affect functional compatibility in standard logic circuits.

Q: Are the packaging options interchangeable?

A: All substitute parts use the 14-TSSOP surface mount package with identical physical dimensions (0.173" width, 4.40mm). Packaging format differences (Cut Tape & Digi-Reel® versus Tape & Reel) relate to supply and handling only and do not affect component functionality or PCB assembly compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 rating, matching the original SN74ACT04PWRE4 specifications.

Q: Which substitute part should be selected for new designs?

A: SN74ACT04PWR is recommended for new designs as the active Texas Instruments equivalent. The onsemi alternatives (74ACT04MTCX and MC74ACT04DTR2G) are functionally equivalent and may be selected based on availability, supply chain considerations, or packaging preferences.
