74AVC2T45GT-Q100X

Overview

The Nexperia 74AVC2T45GT-Q100X is a dual-bit, dual-supply voltage level translator and transceiver featuring three-state outputs. It enables bidirectional translation between low-voltage nodes ranging from 0.8 V to 3.6 V on both ports A and B. The device includes a direction control input (DIR) to manage data flow between the nA and nB ports. Qualified to AEC-Q100 Grade 1 standards, it supports automotive applications with an operating temperature range of -40 °C to +125 °C. It incorporates IOFF circuitry for partial power-down mode operation and provides high noise immunity.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Bidirectional level translation between any low-voltage nodes from 0.8 V to 3.6 V
• IOFF circuitry prevents damaging backflow current during partial power-down
• High ESD protection exceeding 8000 V HBM and 1000 V CDM

Applications

• Automotive electronic systems requiring mixed voltage interfaces
• Translating between different low-voltage logic levels such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V
• Partial power-down applications where one supply rail is grounded while the other remains active

Procurement Notes

Verify that the ordering suffix GT corresponds to the XSON8 package (SOT833-1). Confirm the Q100 designation indicates AEC-Q100 Grade 1 automotive qualification. Ensure the specific variant matches the required temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before purchase.

Selection Notes

Select this component when designing circuits that require bidirectional translation between two independent low-voltage domains within the 0.8 V to 3.6 V range. It is suitable for automotive environments due to its AEC-Q100 Grade 1 qualification and extended temperature rating. Consider the XSON8 package for space-constrained designs requiring leadless terminals. Ensure the system design accounts for the DIR pin control mechanism to prevent bus contention during direction changes.

Part Context

This device belongs to the 74AVC2T45-Q100 family of dual-bit voltage translators manufactured by Nexperia. The 'GT' suffix specifically denotes the XSON8 plastic extremely thin small outline package without leads. The 'Q100' suffix indicates compliance with automotive reliability standards. Other variants in the family include TSSOP8 and VSSOP8 packages, offering flexibility for different board space and thermal requirements.
