SN64BCT757DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN64BCT757DW is an octal buffer and line driver from Texas Instruments, belonging to the BCT logic series. It features eight non-inverting channels with open-collector outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a low-level output current capability of 64 mA and a high-level output current of -15 mA. The typical propagation delay is 7 ns at 5 V. It supports TTL input and output levels and functions across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before integration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest product information sheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-collector outputs are required for multi-driver bus architectures or level shifting. The BCT series offers improved speed compared to standard LS logic while maintaining CMOS power efficiency. Consider the 64 mA sink capability for driving moderate loads directly without additional amplification stages.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SNx4BCT757 family of octal buffers. It serves as a high-speed alternative to older bipolar AS/ALS logic families. The BCT technology combines the speed of Schottky logic with the low power consumption of CMOS, making it suitable for battery-powered and high-density digital designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74AS757DWR is a functional equivalent within the AS logic family, though it lacks open-collector outputs. Verify pinout compatibility and electrical characteristics such as drive strength and voltage tolerance before substitution.
