Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the ACT logic family voltage specifications align with the target system's 5 V rail requirements. Ensure the SOIC-24 footprint matches the printed circuit board layout constraints. Check for any recent lifecycle notices or alternative package recommendations from the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous buffering of multiple data lines without inversion. The ACT series is suitable for applications needing faster switching speeds than standard HC logic while maintaining low power usage. Consider the ±24 mA drive strength for driving long traces or multiple inputs. Verify thermal management needs based on the total active load current drawn by the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT11244 family of octal buffers. It serves as a digital logic interface component designed to isolate stages or amplify signals within 5 V logic systems. The device complements other members of the ACT family, such as inverters and flip-flops, to form complete digital logic solutions. Its standardized pinout facilitates easy integration into existing designs utilizing similar buffer architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the SN74ACT11244DWR variant, which shares identical electrical characteristics but utilizes a reel packaging format instead of cut tape. Other compatible parts within the same logic family may offer different pin counts or inversion types depending on specific circuit requirements.
