Substitute Part Grouping Explanation

Substitute parts for the 74LVC1G240DBVRG4 are determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Inverting
• Number of Elements: 1
• Number of Bits per Element: 1
• Output Type: 3-State
• Current - Output High, Low: 32mA, 32mA
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C (TA)
• Package / Case: SC-74A, SOT-753
• Supplier Device Package: SOT-23-5
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitutes maintain identical electrical and mechanical specifications. Differences exist only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

Both SN74LVC1G240DBVR and SN74LVC1G240DBVT are direct parametric equivalents to the 74LVC1G240DBVRG4. The primary distinction is product status: both substitute parts are currently Active, whereas the original part is Discontinued at DiGi Electronics.

SN74LVC1G240DBVR is designated as the manufacturer-recommended substitute and is available in Cut Tape and Digi-Reel packaging formats with significantly higher inventory (373,100 pcs). SN74LVC1G240DBVT is available in Tape & Reel format with lower inventory (2,000 pcs). Both parts maintain identical electrical specifications, thermal performance, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Selection between these substitutes should be based on packaging requirements and supply chain availability. All three parts are functionally interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are SN74LVC1G240DBVR and SN74LVC1G240DBVT electrically identical to 74LVC1G240DBVRG4?
