Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and environmental compliance status match project requirements. Confirm that the manufacturer designation aligns with current production lines, as component sourcing may vary between original equipment manufacturers and authorized distributors. Ensure all documentation references the latest revision to guarantee accurate electrical specifications and mechanical dimensions are applied during design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-speed, 20-bit parallel interface is required within standard 5V logic families. The ACT series offers improved speed compared to older LS variants while maintaining compatibility. Consider the SSOP package constraints regarding pin pitch and board space. Evaluate the need for three-state buffering to prevent bus contention in complex multi-master architectures where multiple devices share common data pathways.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT logic family, designed for advanced CMOS technology. It serves as a successor to earlier 74LS and 74HC equivalents, offering faster switching speeds suitable for modern digital systems. The 74ACT16861 specifically addresses applications needing wide data path transfers without the complexity of separate latch circuits, integrating both direction control and output enable functions into a single monolithic device.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ACT16861DR is a direct pin-compatible alternative from Texas Instruments using a different package format. Verify that any substitute maintains identical electrical characteristics, particularly propagation delay and output drive strength, to ensure system timing integrity remains unaffected during replacement or upgrade scenarios.
