SN74LVC863APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC863APWR is a 9-bit bus transceiver with 3-state outputs designed for asynchronous communication between data buses. 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 on all ports. The device allows data transmission from the A bus to the B bus or vice versa based on logic levels at the output-enable (OEAB and OEBA) inputs. It includes Ioff circuitry to support partial-power-down mode, preventing damaging current backflow when powered down.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage with 3.3-V VCC
• Includes Ioff circuitry to disable outputs during partial-power-down mode
• Outputs remain in high-impedance state during power-up and power-down conditions

Buffers, Drivers, Receivers, Transceivers Applications

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the TSSOP package and tape-and-reel quantity of 2000 units. Confirm the operating temperature range is -40°C to 85°C. Ensure the RoHS status and lead finish match project requirements. Check for any recent product life cycle changes or discontinuation notices directly from Texas Instruments documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 9-bit bidirectional data transfer with independent control of direction. It is suitable for systems needing compatibility between 3.3-V and 5-V logic levels without external level shifters. Consider the maximum propagation delay of 6.1 ns at 3.3 V for timing constraints. Verify that the 24-pin TSSOP package fits the available PCB footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC863A family of 9-bit bus transceivers. It shares functional characteristics with other variants like SN74LVC863ADW and SN74LVC863APW, differing primarily in packaging and reel specifications. The LVC series is characterized by low-voltage operation and high-speed performance suitable for modern digital logic applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC863APW is a tube-packaged equivalent in the same TSSOP-24 form factor. SN74LVC863ADBR offers the same functionality in a 24-SSOP package.
