SN74LV245ATDW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATDW is an octal bus transceiver manufactured by Texas Instruments, belonging to the LV/LV-A/LVX/H logic series. It features 3-state outputs and operates within a supply voltage range of 2 V to 5.5 V. The device supports bidirectional data transfer between two buses, controlled by direction (DIR) and output enable (OE) inputs. It is housed in a 20-pin HVQCCN package and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode operation allowing ports to interface with differing voltage levels
• Includes Ioff support for partial power-down mode to prevent back-driving currents
• Provides high electrostatic discharge protection exceeding JESD 22 standards

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous bidirectional communication between data buses
• Mixed-voltage system data bus interfaces
• Local shutdown mode applications requiring isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation matches the required footprint, as the 'DW' suffix typically indicates a TSSOP or similar variant depending on the exact datasheet revision. Confirm RoHS compliance status and ensure the operating temperature range aligns with the target environment specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2 V and 5.5 V. It is suitable for applications needing high-speed data transfer with low propagation delay. Ensure the design accounts for the 3-state output characteristics and utilizes the OE pin effectively for bus arbitration.

Buffers, Drivers, Receivers, Transceivers Part Context
