Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC373AD,112 is determined by strict parameter matching across the following critical criteria:

Primary Substitution Criteria:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Package Type: 20-SOIC (0.295", 7.50mm Width)
• Propagation Delay: 1.5ns
• Output Current Capability: 24mA minimum (both high and low)

Voltage Supply Compatibility: Parts with supply voltage ranges that encompass or exceed the original specification (1.2V ~ 3.6V) are considered compatible. Parts with narrower ranges remain functionally equivalent if the overlap covers the intended application voltage.

Temperature Operating Range: The original part operates from -40°C to 125°C. Substitute parts with -40°C to 85°C ranges are acceptable for applications not requiring the extended upper temperature limit.

Compliance & Packaging: All identified substitutes maintain ROHS3 compliance and surface mount configuration. Packaging format variations (Tube, Tape & Reel, Cut Tape) do not affect electrical equivalence but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement: SN74LVC373ADW and SN74LVC373ADWR (Texas Instruments) are recommended as primary substitutes due to active product status, ensuring long-term availability and manufacturer support. Both parts maintain identical electrical specifications to the original 74LVC373AD,112 with supply voltage ranges of 1.65V ~ 3.6V and operating temperature of -40°C ~ 85°C.

For Extended Temperature Range Applications: If the application requires operation at temperatures above 85°C, the 74LVC573AD,112 (Nexperia) maintains the original -40°C ~ 125°C range, though it carries obsolete status. This part is electrically equivalent with identical voltage supply specifications.

For Lowest Moisture Sensitivity: SN74LVC373ADW, SN74LVC373ADWR, and 74LVC573AD,112 all feature MSL Rating 1 (Unlimited), providing superior moisture handling compared to MC74LCX373DWR2G (MSL Rating 3, 168 Hours).

For Maximum Inventory Availability: SN74LVC373ADWR offers the highest current stock level (3300 Pcs), followed by SN74LVC373ADW (2200 Pcs), supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can 74LVC573AD,112 directly replace 74LVC373AD,112? A: Yes. Both parts share identical electrical parameters: D-Type Transparent Latch configuration, 8:8 circuit, tri-state output, 1.2V ~ 3.6V supply voltage, 1.5ns propagation delay, and 24mA output current. The primary difference is packaging format (Tube vs. 20-SO), which does not affect electrical compatibility.

Q: What is the key difference between Nexperia and Texas Instruments substitutes? A: Nexperia parts (74LVC373AD,112 and 74LVC573AD,112) are classified as obsolete, while Texas Instruments parts (SN74LVC373ADW and SN74LVC373ADWR) maintain active product status. Texas Instruments parts have a narrower supply voltage range (1.65V ~ 3.6V vs. 1.2V ~ 3.6V) and reduced operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C).

Q: Is MC74LCX373DWR2G suitable for all applications? A: MC74LCX373DWR2G is electrically equivalent but has two limiting factors: supply voltage range begins at 2V (not 1.2V) and MSL Rating 3 requires controlled moisture exposure during storage and handling. Use this part only when application voltage exceeds 2V and moisture sensitivity protocols are established.

Q: Does packaging format affect substitution compatibility? A: Packaging format (Tube, Tape & Reel, Cut Tape, 20-SO, 20-SOIC) does not affect electrical performance or pin compatibility. Format selection depends on procurement volume, handling procedures, and assembly line requirements. All identified substitutes use the same 20-pin SOIC footprint.

Q: Which substitute offers the best long-term availability? A: SN74LVC373ADW and SN74LVC373ADWR (Texas Instruments) are recommended for long-term projects due to active product status. Nexperia parts carry obsolete classification, indicating potential future discontinuation.
