74LVC1T45GM,132

Translators, Level Shifters Overview

The Nexperia 74LVC1T45GM,132 is a single-bit dual supply translating transceiver with 3-state outputs. It features two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins VCC(A) and VCC(B). Both supplies operate between 1.2 V and 5.5 V, enabling translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Pins A and DIR reference VCC(A), while pin B references VCC(B). The device supports bidirectional transmission controlled by the DIR signal.

Translators, Level Shifters Feature Summary

• Enables bidirectional level translation between any combination of low voltage nodes ranging from 1.2 V to 5.5 V.
• Includes IOFF circuitry that disables outputs during partial power-down to prevent damaging backflow current.
• Features suspend mode where both ports enter high-impedance OFF-state when either supply rail is at GND level.

Translators, Level Shifters Applications

• Partial power-down applications requiring isolation of powered-down sections
• Bidirectional data translation between mixed voltage logic domains
• Systems utilizing multiple independent supply rails for different functional blocks

Translators, Level Shifters Procurement Notes

Verify the specific suffix GM indicates the XSON6 package type SOT886. Confirm the ordering code matches the required temperature range of -40 °C to +125 °C. Ensure the component version aligns with the latest product data sheet revision to guarantee compatibility with design specifications and manufacturing requirements.

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring isolated bidirectional translation between disparate voltage levels within the 1.2 V to 5.5 V range. The inclusion of IOFF circuitry makes it suitable for systems needing safe partial power-down states without external isolation components. Verify that the XSON6 package dimensions fit the available PCB space constraints.

Translators, Level Shifters Part Context

This device belongs to the 74LVC/LVCH family of dual supply translating transceivers manufactured by Nexperia. It shares functional characteristics with variants like the 74LVCH1T45 but lacks active bus hold circuitry. The GM suffix specifically denotes the leadless XSON6 package configuration designed for compact surface-mount applications.

Translators, Level Shifters Replacement Considerations

The 74LVCH1T45GM,132 serves as a direct substitute offering identical functionality with the addition of active bus hold circuitry for floating inputs. Other package variants such as 74LVC1T45GN or 74LVC1T45GW provide equivalent electrical performance in different physical footprints.
