SN74AVCH8T245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH8T245DGVR is an 8-bit dual-supply bus transceiver manufactured by Texas Instruments. It features configurable voltage translation and 3-state outputs, designed for asynchronous communication between data buses. The device utilizes two independent power rails: Port A tracks VCCA (1.2V to 3.6V) and Port B tracks VCCB (1.2V to 3.6V). This architecture enables universal low-voltage bidirectional conversion across nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. It operates within a temperature range of -40°C to +85°C and supports maximum data transmission rates of 320Mbps when both supplies are ≥1.8V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows I/O tolerance up to 4.6V while supporting local shutdown modes via Ioff characteristics.
• Direction control inputs (DIR and OE) utilize logic levels referenced to the VCCA voltage for precise signal routing.
• Provides robust electrostatic discharge protection exceeding JESD 22 standards for human, machine, and charged-device models.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between data buses operating at different voltage levels
• Universal low-voltage bidirectional translation in portable electronic devices
• System isolation using output enable controls to disconnect active buses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to ensure alignment with current manufacturing parameters and pinout configurations before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring flexible voltage translation between multiple low-voltage nodes without external level-shifting circuits. The dual-supply architecture is suitable for applications needing independent power domain management. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range to maintain guaranteed performance metrics.

Buffers, Drivers, Receivers, Transceivers Part Context
