DM74ALS241AN Equivalent & Substitute Parts

Part Overview

The DM74ALS241AN is a non-inverting buffer logic integrated circuit manufactured by onsemi, featuring 2 elements with 4 bits per element and 3-state output capability. This 20-pin DIP package device operates within the 74ALS logic family and is designed for digital signal buffering applications requiring high-speed switching and low power consumption.

The DM74ALS241AN is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and maintenance requirements for systems utilizing this logic buffer.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS241AN are determined by strict equivalence across 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: 15mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Series: 74ALS

All identified substitute parts maintain identical electrical characteristics and mechanical compatibility with the original DM74ALS241AN, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three Texas Instruments substitute parts—SN74ALS241CN, SN74ALS244C-1N, and SN74ALS244CN—are active products with full parametric equivalence to the obsolete DM74ALS241AN. These substitutes are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements for electronic component procurement.

Selection among the three Texas Instruments alternatives should be based on:

• Packaging format availability (all three are supplied in tubes)
• Inventory availability and lead time requirements
• Cost considerations and supplier pricing
• Existing supply chain relationships with Texas Instruments

All three parts provide identical electrical performance and mechanical compatibility for direct replacement in 20-DIP through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS241CN, SN74ALS244C-1N, and SN74ALS244CN be used interchangeably with DM74ALS241AN?

A: Yes. All three Texas Instruments parts maintain identical electrical specifications, output characteristics, supply voltage range, operating temperature range, and 20-DIP package dimensions. Direct pin-for-pin substitution is supported.

Q: What is the difference between the three Texas Instruments substitute parts?

A: The three parts are parametrically equivalent. Differences exist only in manufacturer part numbering (base product numbers 74ALS241 and 74ALS244) and packaging designation. All deliver identical functional performance and electrical characteristics.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Texas Instruments substitute parts are ROHS3 compliant, whereas the original DM74ALS241AN RoHS status was not specified. This compliance status supports modern manufacturing and environmental requirements.

Q: Is the 20-DIP package dimension identical across all parts?

A: Yes. All parts, including the original DM74ALS241AN and all three substitutes, use the 20-DIP (0.300", 7.62mm) package with through-hole mounting. PCB layout and socket compatibility are maintained.

Q: Why is the DM74ALS241AN classified as obsolete?

A: The DM74ALS241AN is an older logic buffer design. Texas Instruments continues to manufacture equivalent 74ALS buffer products in active production, making the onsemi part obsolete while maintaining functional equivalents in the market.
