Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74AC374M96 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same logic function (D-Type flip-flop), element count (1), and bit width (8). Trigger type (Positive Edge) and output type characteristics are preserved across all qualified substitutes.

Mechanical Compatibility: All substitute parts use the identical 20-SOIC (0.295", 7.50mm Width) package, enabling direct physical replacement on printed circuit boards without layout modification.

Supply Voltage Range: Substitute parts operate within voltage ranges that encompass or exceed the original specification (1.5V ~ 5.5V). The onsemi MC74AC374DWR2G and MC74AC374DWG operate at 2V ~ 6V, and the MC74AC377DWR2G operates at 2V ~ 6V, all compatible with standard 5V logic applications.

Compliance & Certification: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the original part.

Packaging Format: Substitutes are available in Tape & Reel (TR) and Tube packaging options, accommodating different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

MC74AC374DWR2G (onsemi): This part is a direct functional equivalent with improved performance characteristics (155 MHz clock frequency, 9.5ns propagation delay). It is supplied in Tape & Reel packaging and maintains Active product status with ROHS3 compliance. The operating temperature range (-40°C ~ 85°C) is narrower than the original part but suitable for standard industrial and commercial applications.

MC74AC374DWG (onsemi): This part provides identical electrical performance to the MC74AC374DWR2G but is supplied in Tube packaging. It is recommended for applications where tube packaging accommodates assembly workflows or inventory management requirements. Active product status and ROHS3 compliance are maintained.

MC74AC377DWR2G (onsemi): This part operates as a D-Type flip-flop with 8-bit configuration and is supplied in Tape & Reel packaging. It exhibits a clock frequency of 140 MHz and propagation delay of 10ns, both superior to the original CD74AC374M96. Active product status and ROHS3 compliance are maintained. The operating temperature range (-40°C ~ 85°C) applies to standard industrial and commercial environments.

All substitute parts are Active products with current manufacturer support and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can MC74AC374DWR2G replace CD74AC374M96 in existing designs?

A: Yes. Both parts share identical logic function (D-Type flip-flop, 1 element, 8-bit), package type (20-SOIC), and pin configuration. The MC74AC374DWR2G operates at higher clock frequency (155 MHz vs. 110 MHz) and lower propagation delay (9.5ns vs. 15.1ns), making it functionally compatible. The supply voltage range (2V ~ 6V) encompasses standard 5V logic applications. Operating temperature range differs (-40°C ~ 85°C vs. -55°C ~ 125°C); verify application requirements if extended temperature operation is required.

Q: What is the difference between MC74AC374DWR2G and MC74AC374DWG?

A: Both parts are electrically identical with the same logic function, performance specifications, and package type (20-SOIC). The primary difference is packaging format: MC74AC374DWR2G is supplied in Tape & Reel (TR), while MC74AC374DWG is supplied in Tube. Selection depends on assembly process requirements and inventory management practices.

Q: Is MC74AC377DWR2G compatible with CD74AC374M96?

A: MC74AC377DWR2G is mechanically and electrically compatible, sharing the same 20-SOIC package, D-Type flip-flop function, 1 element, and 8-bit configuration. Performance is superior (140 MHz clock frequency, 10ns propagation delay). However, the base product number differs (74AC377 vs. 74AC374), indicating a distinct part variant. Verify datasheet pin assignments and functional specifications for the specific application before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (MC74AC374DWR2G, MC74AC374DWG, MC74AC377DWR2G) are ROHS3 compliant and REACH Unaffected, meeting regulatory requirements equivalent to the original CD74AC374M96.

Q: What packaging options are available for substitutes?

A: MC74AC374DWR2G and MC74AC377DWR2G are supplied in Tape & Reel (TR) packaging. MC74AC374DWG is supplied in Tube packaging. Selection depends on assembly process compatibility and procurement requirements.

Q: Do substitute parts support the full operating temperature range of the original part?

A: No. The original CD74AC374M96 operates from -55°C ~ 125°C. All substitute parts (onsemi) operate from -40°C ~ 85°C. For applications requiring extended temperature operation below -40°C or above 85°C, the original part or alternative sources must be evaluated.
