SN74BCT757DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT757DW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the BCT logic series. It features eight non-inverting buffers with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current of 64 mA. Designed for surface-mount applications, it functions reliably across an operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffer channels for signal driving

• Utilizes BiCMOS technology for high-speed performance

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering busses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the 20-pin SOIC package variant when sourcing. Confirm RoHS compliance status as indicated in official datasheets. Ensure the intended application falls within the specified 0°C to +70°C industrial temperature range. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-drive capability on bidirectional buses. The BCT series offers speed comparable to ALS logic with CMOS power consumption. Consider the 64 mA low-level sink current for heavy capacitive loads. Verify that the 4.5 V minimum supply voltage aligns with the system's power rails before integration.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SN74BCT family, which bridges the gap between standard CMOS and TTL logic speeds. The octal configuration allows for efficient handling of wide data paths. It serves as a direct replacement for older AS or ALS octal buffers in high-density PCB layouts where space and drive strength are critical constraints.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74BCT757DWR (tape and reel) if automated assembly is required. Verify pinout compatibility with SN74AS757 variants, noting potential differences in drive strength and power consumption.
