CD74ACT574M96 Equivalent & Substitute Parts

Part Overview

The CD74ACT574M96 is a D-type flip-flop logic integrated circuit manufactured by Texas Instruments, designed for 8-bit data storage and transfer applications. This device operates as a single element with 8 bits per element, featuring tri-state non-inverted outputs and positive edge triggering. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit functional equivalents from alternative manufacturers. The 74ACT logic family provides multiple compatible alternatives across different manufacturers and packaging options.

• Logic family: 74ACT series
• Mounting type: Surface Mount
• Output configuration: Tri-State or Non-Inverted outputs
• Trigger type: Positive Edge
• Supply voltage range: 4.5V ~ 5.5V
• Number of elements: 1
• Number of bits per element: 8

Acceptable Parameter Variations:

• Clock frequency: May be equal to or greater than 110 MHz
• Propagation delay: May be equal to or less than 11.2 ns
• Operating temperature range: May be narrower than -55°C ~ 125°C
• Input capacitance: May be lower than 10 pF
• Moisture sensitivity level: May be higher (MSL 3 acceptable for non-critical applications)
• Packaging format: Tube or Tape & Reel both acceptable
• Product status: Active preferred; Obsolete parts listed for reference only

The substitute parts listed below meet these criteria and are functionally compatible with the CD74ACT574M96 in standard 74ACT logic applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (74ACT574 Base Product):

MC74ACT574DWR2G and MC74ACT574DWG are direct functional equivalents manufactured by onsemi. Both maintain the tri-state non-inverted output configuration and identical supply voltage specifications. The onsemi variants feature improved propagation delay (11 ns versus 11.2 ns) and lower input capacitance (4.5 pF versus 10 pF). Operating temperature range is narrower (-40°C ~ 85°C versus -55°C ~ 125°C), which is acceptable for standard commercial and industrial applications. Moisture sensitivity increases to MSL 3, requiring controlled storage conditions. MC74ACT574DWR2G is supplied in Tape & Reel format; MC74ACT574DWG is supplied in Tube format.

Alternative Substitutes (74ACT374 Base Product):

MC74ACT374DWR2G and MC74ACT374DWG are functionally compatible alternatives with enhanced performance characteristics. Clock frequency increases to 160 MHz and propagation delay improves to 10 ns. These parts maintain tri-state non-inverted output configuration and identical supply voltage and output current specifications. Operating temperature and moisture sensitivity parameters match the onsemi 74ACT574 variants. MC74ACT374DWR2G is supplied in Tape & Reel format; MC74ACT374DWG is supplied in Tube format.

Limited Substitutes (74ACT377 Base Product):

MC74ACT377DWR2G and MC74ACT377DWG are compatible alternatives with non-inverted output configuration (without tri-state capability). Clock frequency is 140 MHz with 10 ns propagation delay. MC74ACT377DWR2G maintains active product status and is supplied in Tape & Reel format. MC74ACT377DWG is obsolete and supplied in Tube format; use only when new stock is unavailable and design permits non-tri-state output operation.

Compliance Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part specifications. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT574DWR2G replace CD74ACT574M96 in all applications?

A: MC74ACT574DWR2G is functionally compatible for applications operating within -40°C ~ 85°C temperature range. If your design requires the extended -55°C ~ 125°C operating range of the CD74ACT574M96, this substitute is not suitable. Both parts maintain identical supply voltage (4.5V ~ 5.5V), output current (24mA), and tri-state non-inverted output configuration. Moisture sensitivity increases from MSL 1 to MSL 3, requiring controlled storage and handling.

Q: What is the difference between 74ACT574 and 74ACT374 variants?

A: Both are 8-bit D-type flip-flops in 20-SOIC packages with identical electrical specifications for supply voltage, output current, and quiescent current. The 74ACT374 offers superior performance with 160 MHz clock frequency and 10 ns propagation delay compared to the 74ACT574's 110 MHz and 11.2 ns. The 74ACT374 is a direct upgrade path when higher speed performance is acceptable.

Q: What does MSL 3 (168 Hours) mean compared to MSL 1 (Unlimited)?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before requiring baking. MSL 1 parts have unlimited shelf life under standard conditions. MSL 3 parts must be used within 168 hours of package opening. If your manufacturing process includes extended storage or high-humidity environments, verify compliance with your moisture control procedures before selecting MSL 3 substitutes.

Q: Can I use MC74ACT377DWR2G as a substitute?

A: MC74ACT377DWR2G is compatible only if your circuit design does not require tri-state output capability. The 74ACT377 provides non-inverted outputs without tri-state control, whereas the CD74ACT574M96 provides tri-state non-inverted outputs. If your design uses the tri-state output enable function, this substitute is not suitable. MC74ACT377DWG is obsolete; prioritize MC74ACT377DWR2G if non-tri-state operation is acceptable.

Q: What packaging format should I select?

A: Tape & Reel (TR) format is standard for automated assembly and high-volume production. Tube format is suitable for manual assembly or lower-volume applications. Both formats contain identical die and electrical specifications. Select based on your manufacturing process requirements. MC74ACT574DWR2G, MC74ACT374DWR2G, and MC74ACT377DWR2G are supplied in Tape & Reel. MC74ACT574DWG, MC74ACT374DWG, and MC74ACT377DWG are supplied in Tube.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the CD74ACT574M96 specifications. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.
