74LVC2T45GT-Q100X

Translators, Level Shifters Overview

The Nexperia 74LVC2T45GT-Q100X is a dual-bit, dual-supply translating transceiver with 3-state outputs. It enables bidirectional level translation between any low voltage nodes ranging from 1.2 V to 5.5 V on both ports A and B. The device features two 2-bit input-output ports (nA and nB), a direction control input (DIR), and separate supply pins VCC(A) and VCC(B). Pins nA and DIR are referenced to VCC(A), while pins nB are referenced to VCC(B).

Translators, Level Shifters Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard.
• IOFF circuitry provides partial power-down mode operation preventing damaging backflow current.
• Active bus hold circuitry holds unused or floating data inputs at a valid logic level.
• ESD protection exceeds 4000 V for HBM and 1000 V for CDM.

Translators, Level Shifters Applications

• Partial power-down applications requiring IOFF functionality.
• Bidirectional level translation between different low voltage nodes.
• Automotive electronic systems requiring AEC-Q100 Grade 1 compliance.

Translators, Level Shifters Procurement Notes

Verify the specific package variant against the ordering information table, as the GT suffix denotes the XSON8 package. Confirm that the required temperature range aligns with the -40 °C to +125 °C specification listed for this part number. Ensure the design accommodates the dual supply requirements for VCC(A) and VCC(B) within the 1.2 V to 5.5 V operating limits.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between arbitrary voltages within the 1.2 V to 5.5 V range is required. The inclusion of active bus hold circuitry distinguishes it from non-bus hold variants like the 74LVC2T45-Q100. Verify that the application environment meets the automotive qualification standards if used in vehicle electronics.

Translators, Level Shifters Part Context

This device belongs to the 74LVC/LVCH2T45-Q100 family of dual supply translating transceivers. It shares functional similarities with the 74LVCH2T45-Q100 but lacks the latter's specific LVCH characteristics. The GT suffix indicates the XSON8 leadless package, distinct from the DC (VSSOP8) or GS (XSON8) package options available in the same series.

Translators, Level Shifters Replacement Considerations

The 74LVCH2T45GT-Q100X is a functionally similar alternative within the same family. Verify pin compatibility and check if the active bus hold feature is required, as the base 74LVC2T45-Q100 does not include this circuitry.
