74AVC20T245BX,518

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AVC20T245BX,518 is a 20-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It supports bidirectional level translation between low voltage nodes ranging from 0.8 V to 3.6 V. The device features two independent 10-bit sections (1An/1Bn and 2An/2Bn), each with dedicated direction control (DIR) and output enable (OE) inputs. It includes IOFF circuitry for partial power-down applications and meets JEDEC standards for various voltage levels.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable bi-directional voltage level translation across dual supplies
• IOFF circuitry prevents damaging backflow current during partial power-down
• Suspend mode ensures high-impedance OFF-state when either supply is at GND

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down system architectures
• Bi-directional data bus interfacing between different voltage domains
• Low voltage translation in mixed-signal environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the BX designation aligns with the intended manufacturing lot or packaging specification. Ensure compatibility with the target PCB footprint and soldering profile before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 20-bit wide bi-directional data paths with independent voltage domain translation. It is suitable for applications needing robust ESD protection and defined suspend modes. Verify that the operating voltage ranges of both sides fall within the specified 0.8 V to 3.6 V limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AVC series of translating transceivers designed for low-voltage applications. It provides a solution for connecting logic families operating at different supply voltages without external level-shifting components. The device integrates direction control and output enable functions directly into the transceiver architecture.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same family if package availability is an issue. Ensure any substitute maintains the same dual-supply voltage range and IOFF functionality.
