Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74LS241N is determined by strict alignment of the following electrical and mechanical parameters:

• Logic type classification: Buffer, Non-Inverting
• Element and bit configuration: 2 elements, 4 bits per element
• Output current specifications: 15mA (high), 24mA (low)
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: 0°C ~ 70°C
• Physical package: 20-DIP (0.300", 7.62mm)
• Mounting configuration: Through Hole

The SN74LS241N from Texas Instruments meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS241N from Texas Instruments is the direct equivalent for the obsolete DM74LS241N. Both components share identical electrical specifications and physical packaging, ensuring pin-for-pin compatibility in existing circuit designs.

The SN74LS241N carries Active product status, providing long-term availability and supply chain stability compared to the obsolete DM74LS241N. Additionally, the SN74LS241N meets ROHS3 compliance requirements, whereas the DM74LS241N is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the SN74LS241N is the appropriate selection.

Both components maintain REACH Unaffected status and EAR99 export classification, with identical HTSUS coding (8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the SN74LS241N directly replace the DM74LS241N in existing applications?
