CD74ACT273MPWREP Equivalent & Substitute Parts

Part Overview

The CD74ACT273MPWREP is a Logic category integrated circuit functioning as a Flip Flop with 1 Element D-Type configuration, 8-bit capacity, and positive edge triggering. Manufactured by Texas Instruments in a 20-TSSOP surface mount package, this device is classified as Obsolete product status. Due to its obsolete classification and limited ongoing availability, identifying equivalent substitute parts is necessary for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitute parts for the CD74ACT273MPWREP are identified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Criteria:

• Series designation (74ACT logic family)
• Package type (20-TSSOP surface mount)
• Functional configuration (D-Type Flip Flop, 1 Element, 8-bit)
• Trigger type (Positive Edge)
• Output type (Non-Inverted)
• Supply voltage range (4.5V ~ 5.5V)
• Output current capability (24mA High, 24mA Low)
• Quiescent current (8 µA)
• RoHS and REACH compliance status

The MC74ACT273DTR2G from onsemi meets all core compatibility requirements while offering improved performance characteristics and Active product status.

Parameter Comparison

Engineering Selection Recommendations

The MC74ACT273DTR2G is a direct functional substitute for the CD74ACT273MPWREP. Both devices share identical core specifications including package type, logic family, bit configuration, and electrical characteristics. The substitute part offers Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the original part.

Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for electronic component deployment. The MC74ACT273DTR2G demonstrates improved performance metrics with higher clock frequency (200 MHz vs. 85 MHz) and reduced propagation delay (11ns vs. 14.6ns), while maintaining backward compatibility with existing designs.

The operating temperature range of the substitute part (-40°C ~ 85°C) is narrower than the original (-55°C ~ 125°C). Design applications requiring operation below -40°C or above 85°C must retain the original CD74ACT273MPWREP or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the MC74ACT273DTR2G replace the CD74ACT273MPWREP in existing designs?

A: Yes. Both parts are 74ACT series D-Type Flip Flops with identical 20-TSSOP packaging, 8-bit configuration, and electrical specifications including supply voltage (4.5V ~ 5.5V), output current (24mA), and quiescent current (8 µA). Pin-to-pin compatibility is maintained.

Q: What are the key differences between these parts?

A: The MC74ACT273DTR2G offers improved performance with 200 MHz clock frequency versus 85 MHz, and 11ns propagation delay versus 14.6ns. The substitute part has Active product status versus Obsolete. The operating temperature range differs: -40°C ~ 85°C for the substitute versus -55°C ~ 125°C for the original.

Q: Are there packaging differences?

A: Both parts use identical 20-TSSOP (0.173", 4.40mm Width) surface mount packages. The MC74ACT273DTR2G is supplied in Tape & Reel (TR) packaging format.

Q: Do both parts meet compliance requirements?

A: Yes. Both the CD74ACT273MPWREP and MC74ACT273DTR2G are ROHS3 Compliant and REACH Unaffected, meeting standard regulatory requirements for electronic components.

Q: What should I consider when selecting between these parts?

A: For new designs or procurement, the MC74ACT273DTR2G is recommended due to Active product status and improved performance characteristics. For applications requiring operation at temperatures below -40°C or above 85°C, verify compatibility with the narrower operating range or identify alternative solutions.
