SN74AVC8T245PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC8T245PWRE4 is an 8-bit dual-supply bus transceiver from Texas Instruments, designed for configurable voltage-level shifting. It operates with supply voltages ranging from 1.2 V to 3.6 V on both ports and supports data rates up to 320 Mb/s. The device features 3-state outputs and a propagation delay of 2.5 ns. It is housed in a 24-TSSOP package and functions within a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-supply architecture allowing independent voltage levels for Port A and Port B
• Bidirectional asynchronous data communication between different voltage domains
• Integrated Ioff circuitry providing partial power-down protection to prevent backflow current

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level translation between low-voltage processors and higher-voltage peripherals
• Data routing in systems requiring isolation between distinct power rails
• High-speed bidirectional bus interfaces in industrial and consumer electronics

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm RoHS compliance and material composition details. Confirm that the 24-TSSOP package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing logic families with mismatched supply voltages, such as 1.2V to 3.3V transitions. The dual-supply design offers flexibility compared to single-supply translators. Consider the 320 Mb/s speed capability for high-bandwidth applications. Verify that the control pins reference the correct supply rail for your direction and enable logic requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC8T245 family of dual-supply bus transceivers. It serves as a bridge for data transfer between circuits operating at different voltage potentials. The device integrates level-shifting capabilities directly into the transceiver structure, eliminating the need for external components typically required for voltage adaptation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC8T245PWR is a recommended manufacturer substitute with identical electrical characteristics but potentially different packaging or reel specifications. Verify pin compatibility and functional equivalence before substitution.
