74LVTH374WM Equivalent & Substitute Parts

Part Overview

The 74LVTH374WM is a D-type flip-flop logic integrated circuit manufactured by onsemi, featuring 1 element with 8-bit parallel data storage capability. This device operates as a positive edge-triggered flip-flop with tri-state, non-inverted outputs in a 20-SOIC surface mount package. The 74LVTH374WM is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain functional equivalence while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVTH374WM are qualified based on strict electrical and mechanical parameter alignment within the 74LVTH logic family. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Series: 74LVTH (same logic family)
• Type: D-Type Flip-Flop (identical function)
• Number of Elements: 1 (single element configuration)
• Number of Bits per Element: 8 (8-bit parallel storage)
• Output Type: Tri-State, Non-Inverted (identical output configuration)
• Trigger Type: Positive Edge (same clock edge sensitivity)
• Package / Case: 20-SOIC (0.295", 7.50mm Width) (identical pinout and footprint)
• Voltage - Supply: 2.7V ~ 3.6V (compatible supply range)
• Operating Temperature: -40°C ~ 85°C (TA) (identical temperature range)

The substitute parts SN74LVTH374DW and SN74LVTH374DWR, manufactured by Texas Instruments, meet all critical matching parameters and are therefore functionally equivalent to the 74LVTH374WM.

Parameter Comparison

Engineering Selection Recommendations

Both SN74LVTH374DW and SN74LVTH374DWR are direct functional equivalents to the 74LVTH374WM. Selection between these substitute parts is determined by packaging and supply chain requirements:

SN74LVTH374DW is supplied in Tube packaging and is suitable for applications requiring standard component quantities with conventional handling and storage.

SN74LVTH374DWR is supplied in Tape & Reel (TR) packaging and is optimized for high-volume production environments utilizing automated pick-and-place assembly equipment.

Both substitute parts are manufactured by Texas Instruments with Active product status, ensuring long-term availability and supply continuity. Both parts are ROHS3 Compliant and maintain REACH Unaffected status, meeting current environmental and regulatory requirements. The Texas Instruments parts demonstrate superior propagation delay performance (4.5ns versus 4.9ns) while maintaining all other electrical specifications within the 74LVTH logic family standard.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH374DW and SN74LVTH374DWR be used interchangeably with 74LVTH374WM?

A: Yes. Both Texas Instruments parts are functionally equivalent to the 74LVTH374WM. They share identical logic family designation (74LVTH), flip-flop type (D-Type), element configuration (1 element, 8-bit), output type (tri-state, non-inverted), trigger type (positive edge), package (20-SOIC), supply voltage range (2.7V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The primary difference is packaging format: Tube versus Tape & Reel.

Q: What is the difference between SN74LVTH374DW and SN74LVTH374DWR?

A: Both parts are electrically identical. The difference is packaging only. SN74LVTH374DW is supplied in Tube packaging for standard component handling. SN74LVTH374DWR is supplied in Tape & Reel (TR) packaging for automated assembly processes. Selection depends on production methodology and supply chain requirements.

Q: Are the substitute parts pin-compatible with the 74LVTH374WM?

A: Yes. All three parts use the identical 20-SOIC (0.295", 7.50mm Width) package with the same pinout. Direct board-level substitution is possible without PCB redesign.

Q: Do the substitute parts meet current regulatory requirements?

A: Yes. Both SN74LVTH374DW and SN74LVTH374DWR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The 74LVTH374WM does not specify RoHS status.

Q: What is the performance difference between the 74LVTH374WM and the substitute parts?

A: The substitute parts demonstrate improved propagation delay performance. Maximum propagation delay is 4.5ns for the Texas Instruments parts versus 4.9ns for the onsemi part, both measured at 3.3V with 50pF load. Clock frequency specification is 150 MHz for the substitute parts versus 160 MHz for the original part. All other electrical parameters remain identical.

Q: Why is the 74LVTH374WM classified as obsolete?

A: The 74LVTH374WM is an onsemi product that has reached end-of-life status. Texas Instruments continues to manufacture functionally equivalent parts (SN74LVTH374DW and SN74LVTH374DWR) with Active product status, ensuring continued availability for new designs and production requirements.
