SN74AVCH8T245PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH8T245PW is an 8-bit dual-supply bus transceiver from Texas Instruments, designed for asynchronous communication between data buses. It features configurable voltage translation capabilities, supporting A and B ports with independent power rails ranging from 1.2V to 3.6V. This allows universal low-voltage bidirectional conversion between nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device operates within a temperature range of -40°C to +85°C and utilizes a 24-pin TSSOP package.

• Supports universal low-voltage bidirectional level translation across multiple voltage nodes
• Features VCC isolation characteristics allowing fully configurable dual-rail design
• Includes Ioff support for partial shutdown mode operation to minimize power consumption

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Bidirectional voltage translation between different logic levels
• System designs requiring configurable dual-supply power rails

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-24 tube packaging configuration. Confirm that the AVCH series designation indicates the inclusion of VCC isolation features compared to standard AVC variants. Ensure compatibility with the required voltage ranges for both A and B ports before integration into the final design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require flexible voltage translation between disparate logic families operating at different supply voltages. The dual-supply architecture makes it suitable for interfaces where one side operates at a lower voltage than the other. Consider the 24-pin TSSOP package constraints for PCB layout and thermal management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVCH8T245 family of 8-bit bus transceivers. It is distinct from the SN74AVC8T245 by offering enhanced VCC isolation features. The device serves as a bridge for digital signals in mixed-voltage environments, ensuring reliable data transfer while managing power efficiency through its configurable rail design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC8T245PW: Similar function but lacks VCC isolation features. 74AVCH8T245PW:118 (Nexperia): Pin-compatible alternative with similar specifications.
