74AVC16T245BX,518

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AVC16T245 is a 16-bit dual-supply translating transceiver with configurable voltage translation and 3-state outputs. It supports bidirectional level shifting between VCC(A) and VCC(B), both ranging from 0.8 V to 3.6 V, enabling translation among 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V levels. The device features two independent 8-bit sections, each with dedicated output enable (nOE) and direction control (nDIR) inputs. It includes IOFF circuitry for partial power-down protection and operates within an ambient temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable bidirectional voltage translation across multiple low-voltage standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Suspend mode automatically places all ports in high-impedance state when supplies are grounded

Buffers, Drivers, Receivers, Transceivers Applications

• Interfacing mixed-voltage logic systems
• Low voltage translation between different supply domains
• Partial power-down applications requiring backflow prevention

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required for your design, as the 74AVC16T245 is available in TSSOP48 (SOT362-1) and TVSOP48 (SOT480-1). Confirm that the selected version meets your thermal dissipation requirements, as derating curves differ between packages. Ensure input and output voltages remain within the specified absolute maximum ratings to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems with differing supply voltages between 0.8 V and 3.6 V. It is suitable for designs requiring independent direction control for two 8-bit segments. Consider the package options based on PCB space constraints and thermal management needs. Verify compatibility with JEDEC standards relevant to your target voltage levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AVC series of bus transceivers designed for low-voltage applications. It provides flexible voltage translation capabilities without requiring external components for direction control or power-down protection. The dual-supply architecture allows seamless integration between various digital logic families operating at different voltage levels.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for other 16-bit dual-supply translators like the 74AVCH16T245DGG. Verify pinout compatibility and electrical characteristics before substitution. Ensure the alternative part supports the same voltage ranges and package types required by your design.
