Substitute Part Grouping Explanation

Substitute parts for the 74LVC2244APW/AUJ are identified based on strict equivalence of the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 12mA, 12mA
• Voltage - Supply: 1.2V ~ 3.6V
• Operating Temperature: -40°C ~ 125°C (TA)
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Series: 74LVC
• Base Product Number: 74LVC2244

Parts meeting all these parameters are classified as parametric equivalents and may be substituted in applications where the 74LVC2244APW/AUJ is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC2244APW/AUJ and 74LVC2244APW,118 are active production parts from NXP with identical electrical and mechanical specifications. The 74LVC2244APW,118 variant is available in bulk packaging with significantly higher inventory (112,147 pieces) compared to the primary part number. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for equivalent selection in applications requiring the 74LVC2244 buffer function. Selection between these parts should be based on packaging requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC2244APW,118 be used as a direct replacement for the 74LVC2244APW/AUJ?

A: Yes. Both parts share identical electrical parameters, logic configuration, output drive capability, supply voltage range, operating temperature range, and 20-TSSOP package specification. They are parametric equivalents.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. The 74LVC2244APW/AUJ is supplied in standard packaging, while the 74LVC2244APW,118 is supplied in bulk packaging. The ",118" suffix indicates the bulk packaging variant. Electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). No compliance or certification differences exist between the two variants.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters remain constant: 2-element, 4-bit per element configuration, 3-state output type, 12mA output drive current, 1.2V to 3.6V supply voltage range, -40°C to 125°C operating temperature, and 20-TSSOP package specification.

Q: Can this part be used in applications requiring different supply voltages?

A: No. The 74LVC2244 is specified for 1.2V to 3.6V supply voltage operation. Applications requiring different voltage ranges require alternative part selection outside the 74LVC2244 family.
