SN74F241DWR Equivalent & Substitute Parts

Part Overview

The SN74F241DWR is a non-inverting buffer logic IC manufactured by Texas Instruments, featuring 2 elements with 4 bits per element and 3-state output capability in a 20-SOIC surface mount package. The device operates at 4.5V to 5.5V supply voltage with an operating temperature range of 0°C to 70°C. Currently listed as obsolete product status, the SN74F241DWR remains in stock with 945 pieces available. Due to its obsolete classification, identifying parametrically equivalent active alternatives ensures design continuity and supply chain reliability for new production runs and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74F241DWR are qualified based on matching the following critical parameters: logic type (buffer, non-inverting), number of elements (2), bits per element (4), output type (3-state), output current specifications (15mA high, 64mA low), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), package type (20-SOIC), and mounting method (surface mount). All substitute parts maintain identical electrical and mechanical compatibility while differing in logic series designation and product status. The three qualified substitutes—SN74AS244ADWR, SN74BCT244DWR, and SN74F244DWR—represent different logic families (74AS, 74BCT, and 74F respectively) that share the same functional and physical specifications, enabling direct replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, SN74F244DWR is the primary recommended substitute, offering the highest inventory availability (7783 pieces) with active product status and identical electrical and mechanical specifications. SN74BCT244DWR and SN74AS244ADWR provide secondary alternatives with active product status and adequate stock levels (641 and 803 pieces respectively). All three substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility. The selection between 74F, 74AS, and 74BCT logic families depends on existing design qualification and supply chain preferences, as all three deliver equivalent functional performance within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74F244DWR directly replace SN74F241DWR in existing circuit designs? A: Yes. SN74F244DWR provides direct functional and physical replacement, sharing identical logic type, element count, bit configuration, output type, current ratings, supply voltage range, operating temperature, and 20-SOIC package specifications.

Q: What is the difference between 74F, 74AS, and 74BCT logic series? A: These designations identify different logic families within the TTL/CMOS logic hierarchy. For the buffer non-inverting function specified, all three series deliver identical electrical performance within the parameters provided: 15mA/64mA output current, 4.5V–5.5V supply voltage, and 0°C–70°C operating temperature.

Q: Why is SN74F241DWR listed as obsolete? A: Obsolete status indicates Texas Instruments has discontinued active production. Existing inventory remains available, but long-term supply cannot be guaranteed. Active alternatives ensure design continuity for future production requirements.

Q: Are all substitute parts available in the same packaging format? A: Yes. All substitute parts use 20-SOIC surface mount packaging with identical physical dimensions (0.295", 7.50mm width), enabling direct PCB layout compatibility without redesign.

Q: Do substitute parts meet the same compliance standards? A: Yes. All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical REACH and ECCN classifications, ensuring regulatory equivalence.

Q: Which substitute offers the best supply availability? A: SN74F244DWR provides the highest current inventory at 7783 pieces, followed by SN74AS244ADWR (803 pieces) and SN74BCT244DWR (641 pieces).
