74AVCH16T245EV,518

Buffers, Drivers, Receivers, Transceivers Overview

The 74AVCH16T245EV,518 is a 16-bit dual supply translating transceiver manufactured by Nexperia. It features bidirectional voltage translation with configurable levels on independent VCC(A) and VCC(B) supplies ranging from 0.8 V to 3.6 V. The device supports data rates up to 380 Mbit/s for translations between 1.8 V and 3.3 V. It includes I_OFF circuitry for partial power-down protection and active bus-hold circuitry to maintain valid logic levels on floating inputs. Packaged in an XQFN16 (SOT1161) form factor, it operates within a temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-supply voltage translation supporting multiple low-voltage standards
• Integrated I_OFF circuitry prevents damaging backflow current during partial power-down
• Active bus-hold circuitry eliminates the need for external pull-up or pull-down resistors

Buffers, Drivers, Receivers, Transceivers Applications

• Low voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains
• High-speed data interfaces requiring configurable direction control
• Partial power-down applications in portable electronic systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '518' against official Nexperia documentation to confirm packaging details and reel specifications. Ensure the selected variant matches the required XQFN16 package dimensions and thermal characteristics for your PCB layout. Cross-reference the part number with the manufacturer's latest datasheet to confirm compliance with relevant RoHS and REACH regulations before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional translation between widely varying low-voltage logic families. The independent supply rails allow flexibility in interfacing different voltage domains without external level-shifting components. Consider the high data rate capabilities for bandwidth-intensive applications and the integrated protection features for robust operation in suspended power states.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia AVCH logic family, designed for advanced low-voltage applications. It serves as a high-performance alternative to standard translators, offering superior speed and lower power consumption. The 16-bit width allows for efficient parallel data transfer, making it suitable for complex system-on-chip interconnects and memory interface expansions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 16-bit dual-supply translators from the same family, such as the 74AVCH16T245DGG. Verify pin compatibility and electrical parameters when substituting. Ensure that any alternative part maintains the same voltage range support and I_OFF functionality to preserve system integrity.
