SN74AS646NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS646NT is an octal bus transceiver and register featuring three-state outputs, manufactured by Texas Instruments. It belongs to the AS logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides a propagation delay of 9 ns and supports TTL input and output levels. It delivers a low-level output current of 48 mA and a high-level output current of -15 mA. Designed for surface-mount applications, it is housed in a 24-pin SOIC package and functions as a non-inverting bidirectional data path with integrated registration capabilities.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NT' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and voltage levels before integration. Cross-reference datasheet revisions to confirm pinout consistency and electrical characteristics match design requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance is critical, as indicated by the AS series propagation delay. Consider the integrated register feature if data synchronization at the receiving end is necessary. Verify that the 24-pin SOIC package fits the available PCB footprint and that the 3-state outputs align with the bus control logic design.
