74AVC1T45GXZ

Overview

The Nexperia 74AVC1T45GXZ is a single-bit, dual-supply voltage level translator and transceiver featuring 3-state outputs. It enables bidirectional level translation between two logic domains with independent supply voltages VCC(A) and VCC(B), both ranging from 0.8 V to 3.6 V. The device includes a direction control input (DIR) to manage data flow between ports A and B. It supports maximum data rates up to 500 Mbit/s depending on voltage translation pairs. The component operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Dual-supply architecture supporting independent voltage levels for bidirectional translation
• Integrated IOFF circuitry enabling partial power-down mode to prevent backflow current
• High noise immunity with low noise overshoot and undershoot characteristics
• Robust ESD protection exceeding 8000 V HBM and 1000 V CDM standards

Applications

• Bidirectional logic level-shifting between mixed voltage systems
• Unidirectional logic level-shifting applications
• Partial power-down mode operation in portable electronics
• Interfacing low voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V

Procurement Notes

Verify the specific ordering suffix GXZ corresponds to the X2SON6 package (SOT1255-2) when sourcing. Confirm that the manufacturer part number matches the required thermal enhanced package variant. Ensure compatibility with the specified -40 °C to +125 °C operating temperature range for your application environment. Cross-reference the datasheet revision date to ensure access to the latest dynamic characteristics and limiting values.

Selection Notes

Select this component for applications requiring a single-bit bidirectional translator with explicit direction control via the DIR pin. It is suitable for systems needing isolation during power-down states using the IOFF feature. Consider the X2SON6 package for space-constrained designs requiring thermal enhancement. Evaluate the propagation delay specifications against your system's timing requirements at the target supply voltages.

Part Context

This device belongs to the 74AVC1T45 family of dual-supply voltage level translators. The family offers multiple package options including TSSOP6, XSON6, and X2SON6 variants. All variants share identical electrical characteristics and functionality, differing only in physical package dimensions and thermal properties. The 74AVC series is designed for high-speed, low-power applications in modern digital systems.

Replacement Considerations

Other packages within the same functional family, such as 74AVC1T45GW, 74AVC1T45GM, 74AVC1T45GN, and 74AVC1T45GS, are electrically equivalent. These alternatives offer different physical footprints while maintaining the same pinout and performance specifications.
