CD74ACT374M96 Equivalent & Substitute Parts

Part Overview

The CD74ACT374M96 is a D-Type flip-flop logic integrated circuit manufactured by Texas Instruments, featuring 1 element with 8-bit positive edge triggering in a 20-SOIC surface mount package. This device operates across the 4.5V to 5.5V supply range with tri-state, non-inverted outputs and is classified as Active product status. Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for functionally equivalent alternatives from different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74ACT374M96 is determined by the following critical parameters: series designation (74ACT), flip-flop type (D-Type), number of elements (1), bits per element (8), output configuration (tri-state, non-inverted), trigger mechanism (positive edge), supply voltage range (4.5V ~ 5.5V), package type (20-SOIC), and mounting method (surface mount). Parts meeting these core electrical and mechanical specifications are classified as parametric equivalents regardless of manufacturer or packaging format. Variations in clock frequency, propagation delay, operating temperature range, input capacitance, and MSL rating do not disqualify substitution when the primary functional parameters align. Parts with different output types (non-inverted only, without tri-state capability) or different base product numbers represent functional variants and are included only when explicitly listed in the original part's substitute cross-reference.

Parameter Comparison

Engineering Selection Recommendations

CD74ACT574M96 serves as a parametric equivalent with identical electrical specifications and operating temperature range. This Texas Instruments part maintains the same MSL rating of 1 (Unlimited) and differs only in packaging format (Tape & Reel versus tube), making it suitable for high-volume manufacturing environments.

MC74ACT374DWG and MC74ACT374DWR2G are onsemi manufactured alternatives with improved clock frequency (160 MHz versus 110 MHz) and reduced propagation delay (10 ns versus 11.2 ns). These parts operate within a narrower temperature range (-40°C to 85°C) and carry MSL rating 3 (168 Hours). Selection of these parts is appropriate when the narrower operating temperature range meets application requirements and when improved timing performance is beneficial.

MC74ACT574DWG and MC74ACT574DWR2G are onsemi alternatives with tri-state, non-inverted outputs matching the original part's output configuration. Clock frequency is reduced to 100 MHz with 11 ns propagation delay. These parts are suitable when the lower frequency specification is acceptable and when onsemi sourcing is preferred.

MC74ACT377DWG and MC74ACT377DWR2G feature non-inverted output without tri-state capability, representing a functional variant. MC74ACT377DWG carries Obsolete product status and should not be selected for new designs. MC74ACT377DWR2G maintains Active status with 140 MHz clock frequency and 10 ns propagation delay. Selection of this variant requires confirmation that the absence of tri-state output does not conflict with circuit requirements.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT374DWR2G replace CD74ACT374M96 directly?

A: Yes, MC74ACT374DWR2G is electrically compatible as a direct replacement. Both parts share identical output type (tri-state, non-inverted), trigger mechanism (positive edge), supply voltage (4.5V ~ 5.5V), and output current specifications (24mA). The onsemi part offers improved clock frequency (160 MHz versus 110 MHz) and faster propagation delay (10 ns versus 11.2 ns). The primary difference is the narrower operating temperature range (-40°C to 85°C versus -55°C to 125°C) and MSL rating (3 versus 1). Verify that your application's temperature requirements fall within -40°C to 85°C before substitution.

Q: What is the difference between CD74ACT374M96 and CD74ACT574M96?

A: Both parts are Texas Instruments 74ACT series D-Type flip-flops with identical electrical specifications, clock frequency (110 MHz), propagation delay (11.2 ns), and operating temperature range (-55°C to 125°C). The primary distinction is the base product number: 74ACT374 versus 74ACT574. This designation reflects internal logic differences in the flip-flop architecture. Both maintain tri-state, non-inverted outputs and are suitable for equivalent applications. Selection between these parts depends on specific circuit requirements and design intent.

Q: Why does MC74ACT377DWG show Obsolete status?

A: MC74ACT377DWG is marked as Obsolete product status, indicating Texas Instruments or the original manufacturer has discontinued active production and support. For new designs, MC74ACT377DWR2G should be selected instead, which maintains Active status and identical electrical specifications. Existing inventory of the obsolete variant may still be available but should not be specified for new production.

Q: Are all substitute parts available in the same packaging format?

A: No. CD74ACT374M96 is supplied in tube packaging. CD74ACT574M96 is available in Tape & Reel (TR) format. onsemi parts are available in both Tube (DWG suffix) and Tape & Reel (DWR2G suffix) formats. Packaging format selection depends on manufacturing process requirements: tube packaging is typical for lower-volume or manual assembly, while Tape & Reel format is standard for automated pick-and-place assembly. All parts maintain identical 20-SOIC (0.295", 7.50mm Width) physical package dimensions.

Q: What does MSL rating 1 versus MSL rating 3 mean for substitution?

A: MSL (Moisture Sensitivity Level) rating indicates the component's sensitivity to moisture absorption during storage and handling. MSL 1 (Unlimited) means the part has no moisture sensitivity restrictions and can be stored indefinitely without special precautions. MSL 3 (168 Hours) requires that the part be used within 168 hours of the package being opened, or the component must be baked to remove absorbed moisture before use. If your manufacturing process includes extended storage or does not include baking procedures, parts with MSL 1 rating (CD74ACT374M96 or CD74ACT574M96) are preferred. If your process includes standard moisture control and baking, MSL 3 parts are acceptable.

Q: Can MC74ACT377DWR2G be used in place of CD74ACT374M96?

A: MC74ACT377DWR2G is not a direct replacement. While both are 74ACT series D-Type flip-flops with 8-bit configuration and identical supply voltage, the MC74ACT377 has non-inverted output without tri-state capability, whereas CD74ACT374M96 has tri-state, non-inverted output. If your circuit design requires tri-state output for bus-sharing applications, MC74ACT377DWR2G cannot be substituted. If your design does not require tri-state output, this part is electrically compatible with improved clock frequency (140 MHz) and propagation delay (10 ns).
