Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ABT241CMTC is determined by the following critical parameters:

Primary Substitution Criteria:

• Logic type: Buffer, Non-Inverting
• Number of elements: 2
• Number of bits per element: 4
• Output type: 3-State
• Voltage supply range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Output current capability: 32mA (high), 64mA (low)
• Package type: 20-TSSOP or 20-SSOP surface mount

Substitute Categories:

Direct Package Match (20-TSSOP): Parts maintaining identical package footprint and pinout compatibility.

• SN74ABT2241PWR (Texas Instruments)
• SN74ABT241APWR (Texas Instruments)
• SN74ABT241APW (Texas Instruments)
• SN74ABT244APW (Texas Instruments)

Alternative Package Match (20-SSOP): Parts with equivalent electrical specifications but different package dimensions (0.209" vs 0.173" width).

• SN74ABT2241DBR (Texas Instruments)
• SN74ABT241ADBR (Texas Instruments)

All substitute parts are manufactured by Texas Instruments and maintain active product status, ensuring long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package - 20-TSSOP):

Select SN74ABT241APWR or SN74ABT241APW when PCB layout and footprint compatibility are critical. Both parts maintain the 20-TSSOP package dimensions (0.173" width) and deliver the required 32mA/64mA output current specifications. SN74ABT241APWR is supplied in Tape & Reel packaging, while SN74ABT241APW is supplied in Tube packaging. Both are ROHS3 compliant and carry active product status from Texas Instruments.

SN74ABT2241PWR offers an alternative 20-TSSOP option with reduced output low current (12mA vs 64mA). This part is suitable only if the application does not require the full 64mA sink current capability.

SN74ABT244APW provides parametric equivalence in the 20-TSSOP package with full current specifications but uses a different base product number (74ABT244 vs 74ABT241). Functional compatibility exists, but pinout verification is required before selection.

For Alternative Package Consideration (20-SSOP):

SN74ABT241ADBR and SN74ABT2241DBR are available in the 20-SSOP package (0.209" width). SN74ABT241ADBR maintains the full 32mA/64mA output current specification and is recommended if PCB layout permits the wider package footprint. SN74ABT2241DBR provides reduced output low current (12mA) and should be selected only if current requirements allow.

All Texas Instruments substitutes carry ROHS3 compliance and active product status, ensuring regulatory alignment and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can SN74ABT2241PWR or SN74ABT2241DBR be used as direct replacements for 74ABT241CMTC?

A: These parts are functionally compatible but deliver reduced output low current (12mA vs 64mA). They are suitable only if the application does not require the full 64mA sink current capability specified for the original part.

Q: What is the difference between 20-TSSOP and 20-SSOP packages?

A: Both are surface mount packages with 20 pins. The 20-TSSOP has a width of 0.173" (4.40mm), while the 20-SSOP has a width of 0.209" (5.30mm). Pinout and functionality are equivalent, but PCB footprints differ. Verify PCB layout compatibility before selecting the 20-SSOP alternative.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Texas Instruments substitutes listed (SN74ABT2241PWR, SN74ABT241APWR, SN74ABT241APW, SN74ABT244APW, SN74ABT2241DBR, SN74ABT241ADBR) are ROHS3 compliant. The original onsemi part does not specify RoHS status.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is used for automated assembly processes and high-volume production. Tube packaging is used for manual assembly or lower-volume applications. Both contain identical components; packaging differs only in presentation and handling method.

Q: Why is the 74ABT241CMTC classified as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Texas Instruments continues to manufacture equivalent parts in the 74ABT241 and 74ABT2241 series, ensuring design continuity and supply availability.

Q: Can SN74ABT244APW be used as a substitute?

A: SN74ABT244APW is parametrically equivalent in electrical specifications and package type but uses a different base product number (74ABT244). Functional compatibility exists, but pinout verification against the original 74ABT241 is required before PCB integration.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Both the original part and all substitutes carry this rating, meaning standard storage and handling procedures apply without special moisture control requirements.
