SN74AVC8T245QPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC8T245QPWRQ1 is an automotive-grade, 8-bit dual-supply bus transceiver featuring configurable voltage translation and three-state outputs. It supports bidirectional asynchronous data communication between buses operating at different voltage levels within the 1.2V to 3.6V range. The device utilizes a single direction control input (DIR) to determine data flow and an output enable (OE) input to isolate the bus. Designed for robust performance, it includes Ioff partial power-down support to prevent backflow current and VCC isolation functionality that forces all ports to a high-impedance state if either supply rail drops to ground.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-supply architecture enabling flexible voltage translation across independent A and B ports
• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications
• Integrated Ioff circuitry prevents backflow current during partial power-down conditions
• VCC isolation feature ensures high-impedance state protection when supply rails are grounded

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring reliable voltage level shifting
• Bidirectional data bus interfaces between components operating at distinct voltage nodes
• Asynchronous communication links in embedded automotive networks

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and AEC-Q100 compliance. Ensure the package type matches the required PCB footprint. Confirm operational temperature ranges align with system requirements. Validate that the manufacturer source is authorized to guarantee component authenticity and traceability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing automotive circuits requiring bidirectional translation between low-voltage logic domains. It is suitable for interfacing devices with varying supply voltages without external level-shifting resistors. Consider its propagation delay and drive strength relative to bus speed requirements. Verify compatibility with existing control logic signals referenced to VCCA.
