SN74LVC863APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC863APWT 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 on all ports. The device allows asynchronous data transmission between the A and B buses depending on logic levels at the OEAB and OEBA control inputs. It includes Ioff circuitry for partial-power-down mode and latch-up performance exceeding 250 mA per JESD 17. The maximum propagation delay is 6.1 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage with 3.3-V VCC
• Ioff circuitry supports partial-power-down mode preventing damaging current backflow
• 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
• Translator applications in mixed-voltage systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the TVSOP (DGV) package type as indicated in the datasheet's ordering information table. Confirm the manufacturer is Texas Instruments and check the product status against the latest Package Option Addendum to ensure availability. Ensure the component meets RoHS requirements and matches the specified operating temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 9-bit wide bus interface is required within a low-voltage system. It is suitable for designs needing compatibility between 3.3-V and 5-V logic domains due to its 5.5-V input tolerance. Consider the TVSOP package dimensions if space constraints require a smaller footprint compared to standard TSSOP or SOIC options.

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 SN74LVC863APW and SN74LVC863ADBR but differs in physical packaging. The 'T' suffix specifically denotes the TVSOP package configuration, distinguishing it from tube or larger reel packaged alternatives.
