Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HC244N-P2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Logic type classification (Buffer, Non-Inverting)
• Number of elements (2)
• Bits per element (4)
• Output configuration (3-State)
• Output current specifications (7.8mA, 7.8mA)
• Supply voltage range (2V ~ 6V)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Equivalence Criteria:

• Package type (20-DIP)
• Physical dimensions (0.300", 7.62mm)
• Mounting method (Through Hole)

Compliance Equivalence Criteria:

• RoHS3 compliance status
• Active product status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC241N is a direct parametric equivalent to the SN74HC244N-P2. Both components are manufactured by Texas Instruments within the 74HC logic series and maintain identical electrical specifications across all critical parameters: logic function, element configuration, output characteristics, supply voltage range, and operating temperature range.

Both parts are housed in mechanically compatible 20-DIP packages with identical pin spacing and mounting requirements. Both components maintain active product status and ROHS3 compliance certification, ensuring continued availability and regulatory conformance for new designs and production applications.

Selection between these two parts may be based on packaging format availability (tube versus other packaging options) and inventory status at the point of procurement.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC241N replace the SN74HC244N-P2 in existing designs?
