74ACT11074DG4 Equivalent & Substitute Parts

Part Overview

The 74ACT11074DG4 is a dual D-type flip-flop logic integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This component functions as a 2-element D-type flip-flop with complementary outputs, set/preset and reset capabilities, and positive edge triggering. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain functional compatibility while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT11074DG4 is determined by the following critical parameters:

• Functional Type: D-Type flip-flop with 2 elements, 1 bit per element, complementary outputs, set/preset and reset functions, positive edge triggering
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 24mA (high and low), quiescent current 4 µA, operating temperature -40°C ~ 85°C
• Package Compatibility: 14-SOIC (0.154", 3.90mm Width) surface mount package
• Compliance: ROHS3 compliant, MSL 1 (Unlimited)

Substitute parts must maintain identical functional architecture, electrical operating ranges, and package form factor. Variations in clock frequency and propagation delay are acceptable provided the substitute meets or exceeds the original specifications within the same logic family (74ACT series).

Parameter Comparison

Engineering Selection Recommendations

74ACT11074D (Texas Instruments)

This substitute maintains identical electrical specifications and propagation delay characteristics to the original 74ACT11074DG4. The part is manufactured by the same supplier and carries active product status. Selection of this part preserves original performance parameters while ensuring continued availability. Packaging differs only in format (Tube versus standard packaging), with no impact on functional compatibility.

MC74ACT74DG and MC74ACT74DR2G (onsemi)

These onsemi-manufactured substitutes provide functional equivalence with enhanced clock frequency performance (210 MHz versus 125 MHz). Both parts maintain identical supply voltage, output current, quiescent current, and operating temperature ranges. The propagation delay specification of 11ns at 5V, 50pF remains within acceptable operating margins for 74ACT logic applications. Both parts carry active product status and ROHS3 compliance. MC74ACT74DR2G is supplied in Tape & Reel format, while MC74ACT74DG is supplied in Tube format. Selection between these onsemi options depends on packaging and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11074D directly replace the 74ACT11074DG4?

A: Yes. The 74ACT11074D is a direct functional equivalent with identical electrical specifications, propagation delay, and 14-SOIC package form factor. The only difference is packaging format (Tube). Pin configuration and electrical performance are identical.

Q: What are the differences between the Texas Instruments and onsemi substitutes?

A: The Texas Instruments 74ACT11074D maintains the original 125 MHz clock frequency and 8.5ns propagation delay. The onsemi MC74ACT74DG and MC74ACT74DR2G offer higher clock frequency (210 MHz) and slightly higher propagation delay (11ns). All three maintain identical supply voltage, output current, and operating temperature ranges. The functional architecture and pin configuration are equivalent across all substitutes.

Q: Are the onsemi parts (MC74ACT74DG and MC74ACT74DR2G) compatible with the original design?

A: Yes. Both onsemi parts are functionally compatible. The enhanced clock frequency specification (210 MHz) exceeds the original 125 MHz rating, and the propagation delay remains within acceptable operating parameters for 74ACT logic circuits. Both parts maintain the same 14-SOIC package, supply voltage range, output current, and operating temperature specifications.

Q: What is the difference between MC74ACT74DG and MC74ACT74DR2G?

A: Both parts are electrically identical. The difference is packaging format: MC74ACT74DG is supplied in Tube packaging, while MC74ACT74DR2G is supplied in Tape & Reel (TR) format. Selection depends on production volume and handling requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 74ACT11074D, MC74ACT74DG, and MC74ACT74DR2G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part specifications.

Q: Can I use these substitutes in existing PCB designs without modification?

A: Yes. All substitute parts use the identical 14-SOIC (0.154", 3.90mm Width) surface mount package with the same pin configuration. No PCB layout modifications are required.
