Engineering Selection Recommendations

For Direct PCB Replacement (20-SSOP Package):

SN74LVC373ADBR (Texas Instruments) is the primary substitute for the obsolete 74LVC373ADB,112. This part maintains identical package geometry (20-SSOP, 0.209", 5.30mm Width) and electrical specifications, enabling direct PCB replacement without layout modification. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range is -40°C to 85°C, which covers the original part's lower temperature bound but does not extend to 125°C.

SN74LVC373AMDBREP (Texas Instruments) provides an alternative with extended operating temperature range (-55°C to 125°C) in the same 20-SSOP package. This option is suitable for applications requiring the full temperature specification of the original part.

For Functionally Equivalent Substitutes (Alternative Packages):

SN74LVC373AQPWREP (Texas Instruments) offers the same electrical performance in a 20-TSSOP package with extended operating temperature (-40°C to 125°C). This part requires PCB layout modification but maintains full functional compatibility.

SN74LVC373APWR and SN74LVC373APWT (Texas Instruments) are active alternatives in 20-TSSOP packaging with standard operating temperature range (-40°C to 85°C).

74LCX373MTC (Fairchild Semiconductor) is functionally equivalent in 20-TSSOP package but operates at a minimum supply voltage of 2V (versus 1.65V for Texas Instruments variants) and maximum operating temperature of 85°C.

All recommended substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC373ADBR be used as a direct replacement for 74LVC373ADB,112?

A: Yes. SN74LVC373ADBR maintains identical package geometry (20-SSOP) and electrical specifications (8:8 D-Type Transparent Latch, tri-state output, 1.5ns propagation delay, 24mA output current). No PCB layout modification is required. The part is currently in active production status.

Q: What is the difference between 20-SSOP and 20-TSSOP packages?

A: Both are surface-mount packages with 20 pins. The 20-SSOP (Shrink Small Outline Package) has a body width of 0.209" (5.30mm), while the 20-TSSOP (Thin Shrink Small Outline Package) has a body width of 0.173" (4.40mm). These different footprints require separate PCB layout designs and cannot be used interchangeably without board redesign.

Q: Does the supply voltage range difference affect substitution?

A: The original part specifies 1.2V to 3.6V supply range. Most active substitutes (Texas Instruments variants) specify 1.65V to 3.6V, which is a narrower range. If your application operates below 1.65V, verify that the substitute part meets your minimum voltage requirement. The 74LCX373MTC specifies 2V minimum, further restricting low-voltage operation.

Q: Which substitute should I select if my application requires -55°C to 125°C operating temperature?

A: SN74LVC373AMDBREP (20-SSOP package) or SN74LVC373AQPWREP (20-TSSOP package) both support the extended temperature range of -55°C to 125°C. Select based on your PCB package requirement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), consistent with the original 74LVC373ADB,112 specification.

Q: What is the inventory status of these substitute parts?

A: SN74LVC373ADBR has 5200 units in stock. SN74LVC373AMDBREP has 933 units. SN74LVC373AQPWREP has 1033 units. SN74LVC373APWR has 2427 units. SN74LVC373APWT has 2044 units. SN74LVC373APW has 3702 units. 74LCX373MTC has 1305 units. Availability may vary by distributor and time of inquiry.
