74AVCH1T45GM,132

Overview

The Nexperia 74AVCH1T45GM,132 is a single-bit dual-supply voltage level translator and transceiver housed in an XSON6 (SOT886) package. It supports bidirectional translation between supply voltages ranging from 0.8 V to 3.6 V on both ports A and B. The device features 3-state outputs, active bus hold circuitry, and IOFF for partial power-down protection. It complies with JEDEC standards for various voltage levels including JESD8-12 through JESD8C. Maximum data rates reach 500 Mbit/s for 1.8 V to 3.3 V translation. Operating temperature ranges from -40 °C to +125 °C.

Feature Summary

• Bidirectional level translation between dual supplies of 0.8 V to 3.6 V
• Active bus hold circuitry eliminates need for external pull-up or pull-down resistors
• IOFF circuitry disables outputs to prevent backflow current during partial power-down
• High noise immunity with low noise overshoot and undershoot

Applications

• Unidirectional logic level-shifting applications
• Bidirectional logic level-shifting applications
• Partial power-down mode operation systems

Procurement Notes

Verify the ordering suffix ',132' corresponds to the specific reel packaging configuration required for your assembly line. Confirm that the XSON6 (SOT886) package dimensions match your PCB footprint design. Ensure the component meets the required environmental compliance standards such as RoHS and REACH for your target market regulations before finalizing procurement.

Selection Notes

Select this component when a single-channel bidirectional translator is needed with independent supply domains. The XSON6 package is suitable for space-constrained designs requiring extremely thin profiles. Consider the dynamic control via the DIR pin if automatic direction sensing is not required by the system architecture. Verify that the maximum data rate requirements align with the specific voltage translation pairs being utilized.

Part Context

This part belongs to the 74AVCH1T45 family of dual-supply voltage level translators. The 'GM' designation specifically identifies the XSON6 (SOT886) leadless package variant. The '132' suffix indicates the tape and reel packaging format. This family provides CMOS low power dissipation and overvoltage tolerant inputs up to 3.6 V, ensuring compatibility with various logic families defined by JEDEC standards.

Replacement Considerations

The 74AVCH1T45GW is a functional equivalent available in a TSSOP6 (SOT363-2) package. The 74AVCH1T45GN and 74AVCH1T45GS are also functionally identical but utilize different XSON6 package variants with distinct body dimensions. Verify package compatibility when substituting these parts.
