74AUP1T45GN,132

Overview

The Nexperia 74AUP1T45GN,132 is a single-bit translating transceiver in an XSON6 (SOT1115) package. It features dual supply pins VCC(A) and VCC(B), both operating between 1.1 V and 3.6 V. The device supports bidirectional level translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. Pins A and DIR are referenced to VCC(A), while pin B is referenced to VCC(B). Schmitt trigger inputs ensure tolerance for slow rise and fall times. Static power consumption is limited to 0.9 μA maximum at 25 °C.

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 supplies are at GND

Applications

• Interfacing between different low voltage logic nodes
• Partial power-down applications requiring isolation
• Systems with varying supply rails such as 1.2 V to 3.3 V

Procurement Notes

Verify the specific ordering suffix GN corresponds to the XSON6 SOT1115 package configuration required for your PCB layout. Confirm that the component meets RoHS3 compliance standards if mandated by your regional regulations. Ensure the manufacturer part number matches exactly to avoid functional discrepancies in dual-supply configurations.

Selection Notes

Select this component when interfacing two distinct voltage domains within the 1.1 V to 3.6 V range using a single data channel. The XSON6 package is suitable for space-constrained designs. Verify that the DIR control signal aligns with the VCC(A) reference level to correctly manage transmission direction between ports A and B.

Part Context

This device belongs to the 74AUP family of advanced ultra-low power CMOS logic. It is designed for portable and battery-operated applications where minimizing static and dynamic power consumption is critical. The dual-supply architecture allows flexible integration into mixed-voltage systems without external level shifting components.

Replacement Considerations

Direct substitutes include other single-bit translating transceivers from the same family, such as the 74AUP1T45GW or 74AUP1T45GM, provided the package type matches the design requirements.
