74AVC1T45GW-Q100H

Overview

The Nexperia 74AVC1T45GW-Q100H is a single-bit, dual-supply voltage level translator and transceiver with 3-state outputs. It facilitates bidirectional level translation between two logic domains, where both VCCA and VCCB support voltages 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 features IOFF circuitry for partial power-down applications, preventing damaging backflow currents. Qualified to AEC-Q100 Grade 1 standards, it operates within an ambient temperature range of -40 °C to +125 °C and is housed in a TSSOP6 package.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Dual-supply architecture supporting independent voltage levels on ports A and B
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current
• Suspend mode activates when either supply rail is at GND, placing both ports in high-impedance state

Applications

• Bidirectional logic level-shifting between mixed-voltage systems
• Unidirectional logic level-shifting applications
• Automotive electronic circuits requiring robust voltage translation

Procurement Notes

Verify the specific suffix 'GW' corresponds to the TSSOP6 (SOT363-2) package variant during sourcing. Confirm that the 'Q100H' designation aligns with the required automotive grade and halogen-free status. Ensure the ordering information matches the intended temperature range and package dimensions specified in the official datasheet before finalizing procurement.

Selection Notes

Select this component when interfacing low-voltage nodes ranging from 0.8 V to 3.6 V. The device is suitable for designs requiring explicit direction control via the DIR pin rather than auto-direction sensing. Consider the TSSOP6 package constraints for PCB layout. Verify that the system's power-up sequence applies GND first, as no special power-up sequence is required beyond this condition.

Part Context

This part belongs to the 74AVC1T45-Q100 family of dual-supply voltage level translators. The 'GW' suffix specifically identifies the TSSOP6 plastic thin shrink small outline package variant. Other family members include GM (XSON6 SOT886) and GS (XSON6 SOT1202) packages. All variants share identical electrical characteristics and functionality, differing only in physical footprint and lead configuration.

Replacement Considerations

Direct replacements within the same family include 74AVC1T45GM-Q100H and 74AVC1T45GS-Q100H, which offer identical electrical performance in different packages.
