SN74LVC863ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC863ADW is a 9-bit bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/output environments with a 3.3-V VCC. The device provides asynchronous communication between data buses with maximum flexibility in timing control. It includes Ioff circuitry for partial-power-down mode operation to prevent damaging current backflow. The package is a 24-pin SOIC (DW) with an operating free-air temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOIC-24 tube packaging configuration. Confirm the RoHS status and lead finish details against the latest TI Package Option Addendum. Ensure the procurement matches the active production status indicated in official documentation. Check for any specific material type designations or preproduction waivers if applicable to the batch.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 9-bit bidirectional data transfer between buses operating at low voltages. The device is suitable for systems needing 5-V tolerant inputs while powered by lower voltage supplies. Consider the 24-pin SOIC package dimensions for PCB layout constraints. Verify that the required propagation delay and output drive capabilities meet the system's electrical specifications.
