74AUP1T45GM,132

Overview

The Nexperia 74AUP1T45GM,132 is a single-bit translating transceiver in an XSON6 (SOT886) package. It features dual supply pins VCC(A) and VCC(B), both supporting 1.1 V to 3.6 V for bidirectional level translation between low voltage nodes. Pins A and DIR reference VCC(A), while pin B references VCC(B). Schmitt trigger inputs ensure tolerance to slow transitions. The device includes IOFF circuitry for partial power-down protection and supports suspend mode when supplies are at GND.

Feature Summary

• Bidirectional level translation capability between independent voltage domains
• Schmitt trigger action on all inputs for noise immunity
• IOFF circuitry prevents backflow current during partial power-down
• Suspend mode activates high-impedance state when either supply is grounded

Applications

• Interfacing between different low voltage logic nodes
• Partial power-down applications requiring backflow prevention
• Systems requiring bidirectional data translation with direction control

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when interfacing two distinct voltage domains within the 1.1 V to 3.6 V range. Ensure the application requires a single-bit bidirectional translator with direction control. Verify that the XSON6 package dimensions fit the PCB layout constraints. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits.

Part Context

This part belongs to the 74AUP series of advanced ultra-low power CMOS logic devices. The GM suffix indicates the XSON6 package type, which is a leadless plastic extremely thin small outline package. This series is designed for applications demanding low static and dynamic power consumption across a wide supply voltage range.

FAQ

How does the device handle partial power-down?

The integrated IOFF circuitry disables the output to prevent damaging backflow current through the device when it is powered down.

What happens if one supply voltage is at GND?

In suspend mode, when either VCC(A) or VCC(B) is at GND, both ports A and B enter a high-impedance OFF-state.
