SN74BCT244NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT244NSR is an octal buffer and line driver from Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high-level output current of -15 mA and low-level output current of 24 mA. Quiescent current is specified at 10 mA in some documentation, while static current is listed as 8 uA in others. It functions in a non-inverting polarity configuration with eight input and eight output lines. The component is housed in a 20-SOIC package and supports operation temperatures from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific datasheet version for the SN74BCT244NSR, as quiescent current specifications vary between sources (8 uA vs 10 mA). Confirm the package type is 20-SOIC and ensure compatibility with 5V logic levels. Check RoHS compliance status and moisture sensitivity level before integration into production designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring octal buffering with three-state control. Ensure the design environment supports the 4.5V to 5.5V operating voltage range. Compare against SN74HCT244 or SN74AC244 variants if different speed or voltage requirements are needed. Verify pinout compatibility with existing PCB layouts using the 20-SOIC footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments BCT logic family, designed for high-speed performance. It is functionally similar to other octal buffers like the SN74LS244 but offers improved switching characteristics. The NSR suffix indicates a tape and reel packaging format suitable for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74BCT244N and SN74BCT244DWR. For voltage-compatible alternatives, consider SN74HCT244NSR or SN74AC244NSR, noting differences in propagation delay and drive current.
