74AVC2T45DC,125

Overview

The Nexperia 74AVC2T45DC,125 is a dual-bit, dual-supply voltage level translator and transceiver housed in an 8-lead VSSOP package (SOT765-1). It supports bidirectional data translation between two independent power domains, with both VCCA and VCCB operating within a range of 0.8 V to 3.6 V. The device features three-state outputs and a direction control input (DIR) to manage signal flow. It complies with JEDEC standards for various low-voltage nodes and includes IOFF circuitry for partial power-down applications.

Feature Summary

• Enables bidirectional level translation between any low voltage nodes ranging from 0.8 V to 3.6 V
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current during partial power-down
• Provides high noise immunity and low noise overshoot/undershoot characteristics
• Features ESD protection exceeding 8000 V (HBM Class 3B) and 1000 V (CDM Class C3)

Applications

• Partial power-down applications requiring safe isolation between powered and unpowered domains
• Bidirectional logic level-shifting between systems operating at different supply voltages
• Unidirectional logic level-shifting for specific data path requirements

Procurement Notes

Verify the ordering suffix ',125' corresponds to the standard tape and reel packaging configuration as specified by Nexperia. Confirm that the VSSOP-8 package variant matches the required PCB footprint dimensions. Ensure the AEC-Q100 qualification status is not assumed for this specific part number unless explicitly stated in the official datasheet, as automotive variants typically carry distinct suffixes like '-Q100'.

Selection Notes

Select this component when interfacing digital signals between two separate voltage domains within the 0.8 V to 3.6 V range. It is suitable for designs requiring explicit direction control via the DIR pin rather than auto-direction sensing. Consider the 8-lead VSSOP package constraints for space-limited layouts. Verify that the maximum data rate requirements align with the specific voltage translation pairs supported by the AVC family.

Part Context

This device belongs to the 74AVC logic family, designed for advanced low-voltage CMOS applications. It serves as a specialized interface solution within Nexperia's portfolio of bus translators and transceivers. The DC suffix specifically identifies the plastic very thin shrink small outline package variant, distinguishing it from TSSOP or XSON options available in the same functional family.

Replacement Considerations
