74AVC2T45DP,125

Overview

The Nexperia 74AVC2T45DP,125 is a dual-bit, dual-supply voltage level translator and transceiver housed in an 8-lead TSSOP package (SOT505-2). It enables bidirectional level translation between any low-voltage nodes ranging from 0.8 V to 3.6 V. The device features two data input-output ports (nA and nB), a direction control input (DIR), and separate supply pins for each port. It supports maximum data rates up to 500 Mbit/s depending on the specific voltage translation configuration. The component includes IOFF circuitry for partial power-down applications and operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Bidirectional level translation between independent voltage domains
• IOFF circuitry prevents damaging backflow current during partial power-down
• High noise immunity with low noise overshoot and undershoot characteristics

Applications

• Translating between different low-voltage logic nodes
• Partial power-down mode operation in mixed-voltage systems
• Bidirectional data transmission interfaces requiring direction control

Procurement Notes

Verify the ordering suffix matches DP for the TSSOP8 plastic thin shrink small outline package. Confirm the temperature grade corresponds to the -40 °C to +125 °C specification. Ensure the part number aligns with the required dual-supply voltage range and 3-state output functionality as documented in the official product data sheet.

Selection Notes

Select this component when interfacing systems operating at distinct voltage levels within the 0.8 V to 3.6 V range. The DIR pin allows explicit control over data flow direction. Consider the TSSOP8 package dimensions if board space permits. Verify that the application requires bidirectional capability rather than unidirectional shifting.

Part Context

This device belongs to the 74AVC series of voltage level translators manufactured by Nexperia. It is designed for high-speed applications requiring reliable signal integrity across varying supply voltages. The family offers multiple package options including VSSOP and XSON variants for different footprint requirements.

Replacement Considerations

Check for other packages in the same family such as 74AVC2T45DC or 74AVC2T45GT if different mounting styles are needed. Ensure substitute parts maintain the same dual-supply voltage range and 3-state output specifications.
