74LVC2T45DC,125

Overview

The Nexperia 74LVC2T45DC,125 is a dual-bit translating transceiver with 3-state outputs in an 8-pin VSSOP package. It supports bidirectional level translation between two independent supply domains, VCC(A) and VCC(B), both ranging from 1.2 V to 5.5 V. The device features a direction control input (DIR) to manage data flow between port A and port B. It includes IOFF circuitry for partial power-down applications and operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Bidirectional voltage level translation between dual supply domains
• IOFF circuitry prevents backflow current during partial power-down
• Suspend mode activates when either supply rail is at GND level

Applications

• Mixed voltage system interconnects
• Partial power-down bus architectures
• Low voltage node translation interfaces

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the DC designation corresponds to the VSSOP8 plastic very thin shrink small outline package. Ensure the component meets the specified temperature range requirements for the intended operational environment before finalizing procurement.

Selection Notes

Select this component when interfacing logic circuits operating at different voltage levels within the 1.2 V to 5.5 V range. The dual-supply architecture allows flexible configuration for various low voltage nodes. Consider the IOFF feature if the design requires protection against damaging currents during power-down states.

Part Context

This part belongs to the 74LVC/LVCH family of translating transceivers. It provides a compact solution for bidirectional data transfer between disparate voltage domains. The device integrates direction control and output enable functions into a minimal footprint suitable for space-constrained printed circuit board layouts.

Replacement Considerations

The 74LVCH2T45DC,125 serves as a direct functional equivalent within the same product family.
