SN74ACT241PW Equivalent & Substitute Parts

Part Overview

The SN74ACT241PW is a non-inverting buffer logic IC manufactured by Texas Instruments, designed for 2 element, 4-bit per element configurations with 3-state output capability. The device operates across a 4.5V to 5.5V supply range and is housed in a 20-TSSOP surface mount package. This part is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74ACT241PW are grouped based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications 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: 24mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes are differentiated by packaging format (Tube, Cut Tape & Digi-Reel, Tape & Reel), manufacturer (Texas Instruments, onsemi), and product status (Active, Discontinued). Base product numbers may vary (74ACT241 vs. 74ACT244) while maintaining full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the SN74ACT241PW, the following selection criteria apply based on product status and availability:

Active Status Substitutes (Recommended for New Designs):

• MC74ACT241DTR2G (onsemi): Highest inventory availability (20,200 pcs), Tape & Reel packaging, Active product status. Identical electrical specifications and 20-TSSOP package.
• SN74ACT241PWR (Texas Instruments): Active product status, Cut Tape & Digi-Reel packaging, 2,200 pcs available. Direct base product number match (74ACT241) with identical electrical parameters.
• 74ACT244MTC (onsemi): Active product status, Tube packaging, 4,395 pcs available. Parametric equivalent with 74ACT244 base product number.

Discontinued Status Substitutes (Legacy Support Only):

• SN74ACT244PW (Texas Instruments): Discontinued at DiGi Electronics, Tube packaging, 2,200 pcs available. Parametric equivalent with 74ACT244 base product number.
• SN74ACT244PWE4 (Texas Instruments): Discontinued at DiGi Electronics, packaging not specified, 867 pcs available. Parametric equivalent with 74ACT244 base product number.

All substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance across the specified operating temperature range (-40°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can SN74ACT241PWR be used as a direct replacement for SN74ACT241PW? A: Yes. Both parts share identical electrical specifications, logic type, output characteristics, and 20-TSSOP package. The difference is packaging format: SN74ACT241PW uses Tube packaging while SN74ACT241PWR uses Cut Tape & Digi-Reel. SN74ACT241PWR is currently Active status, making it the preferred choice for new procurement.

Q: What is the difference between 74ACT241 and 74ACT244 base product numbers? A: Both base product numbers maintain identical electrical specifications for this application: 2 elements, 4 bits per element, 3-state output, 24mA output current, and 4.5V to 5.5V supply voltage. The base product number difference does not affect functional compatibility in circuits designed for the SN74ACT241PW.

Q: Are onsemi and Texas Instruments substitutes electrically equivalent? A: Yes. MC74ACT241DTR2G (onsemi) and SN74ACT241PWR (Texas Instruments) are electrically equivalent. Both maintain identical logic type, output current ratings, supply voltage range, operating temperature range, and 20-TSSOP package specifications. Selection between manufacturers is based on availability, packaging preference, and procurement requirements.

Q: Does packaging format affect electrical performance? A: No. Tube, Cut Tape & Digi-Reel, and Tape & Reel packaging formats do not affect electrical performance. Selection is based on assembly process requirements and inventory management. All formats maintain identical component specifications and performance characteristics.

Q: Why is MC74ACT241DTR2G recommended despite different packaging? A: MC74ACT241DTR2G offers the highest inventory availability (20,200 pcs) and Active product status. Tape & Reel packaging is standard for automated assembly processes. The part maintains identical electrical specifications and 20-TSSOP package footprint as the original SN74ACT241PW.

Q: Are all substitutes RoHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL Level 1 rating, matching the original SN74ACT241PW specifications.
