SN74LVC863ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC863ANSR 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 and offers ESD protection exceeding JESD standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation on all ports, allowing 5-V input/output voltage compatibility with a 3.3-V VCC supply.
• Includes Ioff circuitry that disables outputs during power-down to prevent damaging current backflow through the device.
• Outputs remain in a high-impedance state during power-up and power-down conditions to ensure system safety.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Mixed 3.3-V/5-V system environment translation
• Partial-power-down applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and tape-and-reel specifications against the manufacturer's latest documentation before procurement. Confirm that the ordering suffix matches the required physical dimensions and pin configuration. Ensure compliance with RoHS directives and check for any recent product life cycle notices or availability changes directly from the supplier.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between buses operating at different voltage levels within the 1.65-V to 3.6-V range. Consider its 5.5-V tolerant inputs for interfacing with legacy 5-V logic without additional level shifting. Evaluate the need for partial-power-down capabilities and high-impedance states during power transitions for your specific application requirements.
