74LVTH652WM Equivalent & Substitute Parts

Part Overview

The 74LVTH652WM is a non-inverting transceiver logic IC manufactured by onsemi, designed for 8-bit bidirectional data transfer with 3-state output capability. Operating at 2.7V to 3.6V supply voltage, this component is housed in a 24-SOP package and rated for -40°C to 85°C operating temperature range. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible functionality.

Substitute Part Grouping Explanation

Substitution for the 74LVTH652WM is determined by strict equivalence across the following critical parameters:

Logic Type: Transceiver, Non-Inverting
Number of Elements: 1
Number of Bits per Element: 8
Output Type: 3-State
Current - Output High / Low: 32mA / 64mA
Voltage - Supply: 2.7V ~ 3.6V
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 24-SOIC (0.295", 7.50mm Width)
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters, ensuring direct functional compatibility in applications originally designed for the 74LVTH652WM.

Engineering Selection Recommendations

For applications currently using the obsolete 74LVTH652WM, the following selection criteria apply:

Primary Recommendation: SN74LVTH652DW (Texas Instruments) provides direct functional equivalence with identical part number base and active product status. This part maintains full compatibility with existing designs and benefits from ongoing manufacturer support and RoHS3 compliance.

Alternative Selections: SN74LVTH543DW, SN74LVTH2952DW, and SN74LVTH646DW are all active Texas Instruments products with equivalent electrical and mechanical specifications. These alternatives are suitable where design flexibility permits functional substitution within the 74LVTH transceiver family.

Avoid: SN74LVTH646DWG4 is discontinued at DiGi Electronics and should not be selected for new designs requiring long-term component availability.

Secondary Option: SN74LVT543DW (74LVT series) is active and fully compatible but represents a different product series. This part is acceptable where cross-series substitution is permitted by design requirements.

All recommended substitutes carry REACH Unaffected status, EAR99 classification, and MSL 1 rating, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH652DW directly replace 74LVTH652WM in existing PCB designs?

A: Yes. Both parts share identical electrical specifications (2.7V ~ 3.6V supply, 32mA/64mA output current, -40°C ~ 85°C operating range) and equivalent package footprints (24-SOIC vs. 24-SOP). The SN74LVTH652DW is the direct Texas Instruments equivalent with active product status.

Q: What is the difference between 24-SOP and 24-SOIC packaging?

A: Both are surface-mount packages with 24 pins and 0.295" (7.50mm) width. The designations reflect different manufacturer naming conventions but represent mechanically and electrically compatible packages suitable for the same PCB footprints.

Q: Are all listed substitutes RoHS compliant?

A: All Texas Instruments substitutes (SN74LVT543DW, SN74LVTH2952DW, SN74LVTH543DW, SN74LVTH646DW, SN74LVTH646DWG4, SN74LVTH652DW) carry RoHS3 Compliant status. The original onsemi 74LVTH652WM does not specify RoHS status in the provided data.

Q: Which substitute has the highest current inventory?

A: SN74LVT543DW maintains the highest inventory at 2152 pieces, followed by SN74LVTH646DW at 1369 pieces. Inventory levels should be confirmed with suppliers for production requirements.

Q: Can I use SN74LVT543DW instead of SN74LVTH652DW?

A: Yes. Both parts meet all electrical and mechanical substitution criteria. SN74LVT543DW represents the 74LVT series variant while SN74LVTH652DW represents the 74LVTH series. Selection depends on design flexibility and availability requirements.
