74AVCH16T245BQ,518

Buffers, Drivers, Receivers, Transceivers Overview

The 74AVCH16T245BQ,518 is a 16-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It supports bidirectional data transfer between two independent power domains ranging from 0.8 V to 3.6 V. The device features active bus hold circuitry to maintain valid logic levels on floating inputs and IOFF circuitry for partial power-down applications. It operates within temperature ranges of -40 °C to +85 °C and -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable voltage translation between independent A and B power supplies
• Active bus hold circuitry eliminates need for external pull-up or pull-down resistors
• IOFF circuitry prevents damaging backflow current during partial power-down
• Suspend mode isolates buses when either supply voltage is at ground level

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional level shifting between low-voltage microcontrollers and higher-voltage peripherals
• Partial power-down systems requiring isolation of powered-off ports
• High-speed data bus interfacing in mixed-voltage embedded environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '518' against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required thermal performance and terminal configuration for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to confirm compliance with current JEDEC standards and RoHS directives before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 16-bit wide buses between different voltage domains. It is suitable for designs requiring high ESD protection and robust latch-up performance. Consider the HXQFN60U package dimensions and thermal requirements. Verify that the maximum data rate requirements align with the specific voltage translation ratios used in the application design.
