SN74BCT756DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT756DW is an octal buffer and line driver featuring open-collector outputs, designed for high-performance memory address drivers, clock drivers, and bus-oriented receivers. It utilizes BiCMOS technology to significantly reduce supply current (ICC). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. Key electrical characteristics include a low-level output current (IOL) of 64 mA and propagation delays (tPLH/tPHL) ranging from 0.5 ns to 11.3 ns depending on conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against project requirements, as the DW suffix denotes a Plastic Small-Outline Package. Confirm RoHS compliance status and lead finish specifications via the manufacturer's latest ordering addendum. Ensure the selected component matches the required operating temperature range and logic family compatibility before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-collector outputs are necessary for wired-AND bus configurations or direct interfacing with higher voltage loads. The BCT series offers superior speed compared to standard TTL while maintaining CMOS input compatibility. Verify that the 64 mA sink capability meets the load requirements and that the 0°C to 70°C industrial temperature range aligns with the environmental constraints of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74BCT logic family, which combines the speed of bipolar circuits with the low power consumption of CMOS inputs. The SN74BCT756 specifically provides eight non-inverting buffers with open-collector outputs, distinguishing it from standard push-pull output variants like the SN74BCT240.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives within the same family include the SN74BCT757 and SN74BCT760. These parts share identical pinouts but differ in output polarity and enable input configurations. Verify functional equivalence regarding output drive type and control logic before substitution.
