74AVC4TD245GU,115

Overview

The Nexperia 74AVC4TD245GU,115 is a 4-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It features eight 1-bit input-output ports (An and Bn), four direction control inputs (DIR1–DIR4), an output enable input (OE), and dual supply pins (VCC(A) and VCC(B)). Both supplies operate between 0.8 V and 3.6 V. The device supports maximum data rates up to 380 Mbit/s for translations ≥1.8 V to 3.3 V. It includes IOFF circuitry for partial power-down applications and operates from -40 °C to +125 °C in an XQFN16 package.

Feature Summary

• Bidirectional level translation between any low voltage nodes within the 0.8 V to 3.6 V range
• Configurable direction control via individual DIR inputs for each channel
• IOFF circuitry prevents damaging backflow current during partial power-down
• Suspend mode isolates buses when either supply rail is at GND level

Applications

• Partial power-down bus isolation
• Bidirectional voltage translation between mixed logic families
• High-speed data bus interfacing with configurable directionality

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the temperature range specification aligns with the intended operational environment. Ensure compatibility with JEDEC standards relevant to the target voltage levels. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when bidirectional translation between arbitrary voltages within the 0.8 V to 3.6 V range is required. The individual direction control inputs allow flexible bus management without external logic. Consider the XQFN16 package dimensions for PCB layout constraints. Verify that the maximum data rate requirements are met by the specific voltage translation scenario being implemented.

Part Context

This device belongs to the 74AVC series of advanced CMOS translators. It is designed for high-speed applications requiring reliable voltage level shifting between different supply domains. The GU suffix indicates the XQFN16 package variant, which offers a compact footprint suitable for space-constrained designs.

Replacement Considerations

Check for direct substitutes within the same family such as the 74AVC4T245GU,115 if unidirectional operation suffices. Verify pin-to-pin compatibility with other 4-bit translators like the 74AVC4TD245BQ if a different package is preferred.
