SN74LV245ATDGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATDGVR is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data transmission. It operates within a supply voltage range of 2V to 5.5V and features three-state outputs. The device utilizes LV/LV-A/LVX/H logic series technology and includes direction control (DIR) and output enable (OE) inputs to manage data flow between two buses. It is housed in a 20-pin TSSOP package with a maximum operating temperature of 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data transfer between A and B buses via DIR input control
• Enables partial power-down protection through Ioff feature to prevent reverse current
• Provides high electrostatic discharge protection exceeding JESD 22 standards

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous bidirectional communication on data buses
• Bus-oriented memory and command/data addressing
• Mixed-mode voltage system interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status and ensure the component matches the SN74LV245A family specifications regarding voltage ranges and pinout definitions before integration into designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation from 2V to 5.5V. It is suitable for systems needing high-speed data transfer with low propagation delay. Ensure the design accommodates the TSSOP-20 footprint and thermal requirements for the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV245A family of octal bus transceivers. It shares functional characteristics with other variants in the LV/LV-A/LVX/H series but differs in package type and manufacturing revision. The DGVR suffix indicates a specific tape-and-reel packaging option for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74LV245A variants with compatible packages such as SN74LV245ADGVR or SN74LV245APWR, provided the pinout and electrical parameters match the original design requirements.
