SN74BCT760DW Equivalent & Substitute Parts

Part Overview

The SN74BCT760DW is a Buffer, Non-Inverting logic IC manufactured by Texas Instruments, featuring 2 elements with 4 bits per element and open collector output configuration. This device operates across a 4.5V to 5.5V supply range and is housed in a 20-SOIC surface mount package. The SN74BCT760DW carries a Last Time Buy product status, indicating limited future availability. Identifying equivalent and substitute parts ensures design continuity and supply chain resilience for applications requiring non-inverting buffer functionality with open collector outputs.

Substitute Part Grouping Explanation

Substitute parts for the SN74BCT760DW are qualified based on identical electrical and mechanical parameters. All substitute candidates maintain the same logic function (Buffer, Non-Inverting), element configuration (2 elements, 4 bits per element), output type (Open Collector), output current rating (64mA), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and package specification (20-SOIC surface mount). Substitution eligibility is determined by these core parameters, which define functional and physical compatibility within the application circuit.

The substitute parts are categorized as follows:

MFR Recommended Substitute: SN74BCT760DWR (same base product number, alternative packaging format)

Parametric Equivalents: SN74AS757DW, SN74AS760DW, SN74BCT757DW (alternative series designations with identical electrical specifications)

Engineering Selection Recommendations

Primary Recommendation: SN74BCT760DWR is the preferred substitute, maintaining the same base product number (74BCT760) and series designation while offering Active product status. This part provides the highest supply assurance and is packaged in Cut Tape (CT) & Digi-Reel® format, suitable for automated assembly processes.

Secondary Recommendations: SN74BCT757DW is an Active product within the same 74BCT series, providing long-term availability. The 74AS series alternatives (SN74AS757DW, SN74AS760DW) are parametrically equivalent but carry Last Time Buy status, limiting their suitability for new designs requiring extended component lifecycle support.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original SN74BCT760DW specification.

Frequently Asked Questions (FAQ)

Q: Can SN74BCT760DWR be used as a direct replacement for SN74BCT760DW?

A: Yes. Both parts share identical electrical parameters (Buffer, Non-Inverting, 2 elements, 4 bits per element, Open Collector output, 64mA output current, 4.5V ~ 5.5V supply, 0°C ~ 70°C operating range) and the same 20-SOIC package. The primary difference is packaging format (Tube versus Cut Tape & Digi-Reel®) and product status (Last Time Buy versus Active).

Q: What is the difference between 74BCT and 74AS series buffers?

A: Both series maintain identical electrical specifications for the SN74BCT760DW and its equivalents. The series designation reflects internal logic family characteristics, but functional and parametric compatibility is preserved across both families for these specific part numbers.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist when substituting between listed parts. All substitute candidates maintain identical logic function, output configuration, electrical ratings, and physical package dimensions. Circuit-level performance remains unchanged.

Q: Why is SN74BCT760DW marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued or will discontinue production. Identifying active alternatives such as SN74BCT760DWR or SN74BCT757DW ensures continued supply availability for ongoing production requirements.

Q: What packaging formats are available for these substitute parts?

A: SN74BCT760DW and SN74AS757DW, SN74AS760DW, SN74BCT757DW are supplied in Tube packaging. SN74BCT760DWR is supplied in Cut Tape (CT) & Digi-Reel® format, optimized for high-volume automated assembly operations.
