Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC244APW/AUJ are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Core Electrical Parameters (Must Match):

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.2V ~ 3.6V
• Operating Temperature: -40°C ~ 125°C (TA)

Mechanical Parameters (Must Match):

• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these requirements. Variations in packaging format (Cut Tape, Digi-Reel, Tape & Reel), manufacturer designation, or series classification (74LVC vs. 74LVCH) do not affect functional or mechanical compatibility when core parameters remain identical.
