SN74LVC863ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC863ADGVR is a 9-bit bus transceiver with 3-state outputs designed for 1.65-V to 3.6-V VCC operation. It supports asynchronous communication between data buses and allows transmission from the A bus to the B bus or vice versa based on OEAB and OEBA logic levels. Inputs accept voltages up to 5.5 V, enabling mixed-mode signal operation in 5-V input/output environments with 3.3-V VCC. The device features Ioff support for partial-power-down mode, preventing damaging backflow current. Outputs remain high-impedance during power-up/down. 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 compatibility with 3.3-V VCC
• Includes Ioff circuitry to disable outputs and prevent backflow current during partial-power-down conditions
• Provides flexible timing control through independent output-enable inputs (OEAB and OEBA) for bidirectional data transfer

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Mixed-mode signal translation in systems combining 5-V and 3.3-V devices
• Partial-power-down applications requiring isolation of powered-down ports

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP package and tape-and-reel quantity of 2000 units. Confirm the operating temperature range matches the application requirements of -40°C to +85°C. Ensure that the RoHS compliance status aligns with environmental regulations applicable to the target deployment region. Cross-reference the manufacturer part number against the latest TI Package Option Addendum to validate active production status and material specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring 9-bit bidirectional data transfer within the 1.65-V to 3.6-V supply range. It is suitable for interfaces needing tolerance to 5-V input signals while operating at lower core voltages. Consider its Ioff capability if the system design mandates protection against backfeeding currents during power-down states. Verify that the TVSOP package dimensions fit the available PCB footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC863A family of 9-bit bus transceivers. It shares functional characteristics with other LVC series components but is distinct in its 9-bit width and specific pinout configuration. The ADGVR suffix indicates a TVSOP package variant manufactured by Texas Instruments. It serves as a standard interface solution for general-purpose digital logic applications requiring level shifting and bus isolation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LVC863ADW, SN74LVC863APWR, and SN74LVC863APWT. These alternatives offer identical electrical functionality but differ in package type (SOIC, TSSOP) or reel quantity. Verify pin compatibility and thermal performance before substitution.
