74AVC1T45GM,132

Overview

The Nexperia 74AVC1T45GM,132 is a single-bit dual-supply voltage level translator and transceiver featuring 3-state outputs. It enables bidirectional level translation between ports A and B, with supply voltages VCC(A) and VCC(B) ranging from 0.8 V to 3.6 V. The device supports maximum data rates up to 500 Mbit/s for 1.8 V to 3.3 V translation. It includes IOFF circuitry for partial power-down applications and operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Bidirectional level translation between two independent low-voltage domains
• IOFF circuitry prevents damaging backflow current during partial power-down
• Suspend mode activates high-impedance state when either supply is at GND
• Dynamically controlled outputs with low noise overshoot and undershoot

Applications

• Partial power-down applications requiring isolation
• Bidirectional logic level-shifting between different voltage nodes
• Unidirectional logic level-shifting with DIR pin tied to ground

Procurement Notes

Verify the ordering suffix '132' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the XSON6 (SOT886) package dimensions align with the target PCB footprint constraints. Ensure the selected component meets the specified RoHS3 compliance standards for the intended manufacturing environment.

Selection Notes

Select this component when interfacing systems operating between 0.8 V and 3.6 V with bidirectional data flow requirements. The 74AVC1T45GM variant provides a leadless XSON6 package suitable for space-constrained designs. Consider the dynamic data rates and propagation delays relative to the specific voltage translation pairs in the application design.

Part Context

This part belongs to the 74AVC family of dual-supply voltage translators manufactured by Nexperia. It shares functional similarities with other single-bit translators but offers specific performance characteristics regarding speed and power consumption. The GM suffix identifies the XSON6 package type, distinguishing it from TSSOP or other leaded variants within the same logical family.

Replacement Considerations

Direct replacements include other 74AVC1T45 variants such as 74AVC1T45GW, 74AVC1T45GN, 74AVC1T45GS, and 74AVC1T45GX, provided the package form factor matches the existing board layout.
