DM74ALS374WMX Equivalent & Substitute Parts

Part Overview

The DM74ALS374WMX is a D-Type flip-flop logic integrated circuit manufactured by onsemi, featuring 1 element with 8-bit capacity and tri-state, non-inverted output configuration. This component operates at a maximum clock frequency of 35 MHz with a propagation delay of 16ns at 5V with 50pF load. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM74ALS374WMX is determined by strict equivalence across the following critical parameters:

• Base Product Number: All substitutes must share the 74ALS374 base designation
• Functional Type: D-Type flip-flop with 1 element, 8-bit configuration
• Output Configuration: Tri-state, non-inverted output
• Electrical Specifications: Clock frequency of 35 MHz, propagation delay of 16ns @ 5V/50pF, output currents of 2.6mA (high) and 24mA (low)
• Supply Voltage: 4.5V ~ 5.5V operating range
• Package: 20-SOIC (0.295", 7.50mm Width) surface mount
• Quiescent Current: 19 mA maximum
• Operating Temperature: 0°C ~ 70°C

The substitute parts SN74ALS374ADW and SN74ALS374ADWR, both manufactured by Texas Instruments, meet all electrical and mechanical equivalence criteria and are therefore direct substitutes for the obsolete onsemi part.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS374ADWR (Texas Instruments) is the primary substitute for the obsolete DM74ALS374WMX. This part carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and production.

SN74ALS374ADW (Texas Instruments) is an alternative substitute with Last Time Buy status. While electrically and mechanically equivalent, this part has limited future availability. It is suitable for legacy system maintenance and repair applications where supply constraints are acceptable.

Both Texas Instruments substitutes maintain complete electrical and mechanical equivalence with the original onsemi part across all specified parameters, including clock frequency, propagation delay, output current ratings, supply voltage range, and package configuration.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS374ADW and SN74ALS374ADWR be used interchangeably with DM74ALS374WMX?

A: Yes. Both Texas Instruments parts are direct electrical and mechanical equivalents. They share identical functional specifications, electrical performance characteristics, and 20-SOIC package configuration. Pin-for-pin compatibility is maintained across all signal and power connections.

Q: What is the difference between SN74ALS374ADW and SN74ALS374ADWR?

A: Both parts are electrically identical with matching specifications. The primary difference is product status: SN74ALS374ADWR is Active with ongoing production, while SN74ALS374ADW is Last Time Buy with limited future availability. For new designs, SN74ALS374ADWR is recommended.

Q: Are there any compliance differences between the substitute parts and the original?

A: The Texas Instruments substitutes (SN74ALS374ADW and SN74ALS374ADWR) are ROHS3 compliant, whereas the original onsemi part is REACH unaffected. Both substitute parts maintain REACH unaffected status. All three parts have MSL rating of 1 (Unlimited).

Q: Is the 20-SOIC package identical across all three parts?

A: Yes. All three parts use the 20-SOIC (0.295", 7.50mm Width) surface mount package with identical pin assignments and mechanical dimensions, enabling direct PCB layout compatibility.

Q: What is the supply voltage requirement for these parts?

A: All three parts operate within the 4.5V ~ 5.5V supply voltage range. They are compatible with standard 5V logic systems and require no voltage adjustment for substitution.
