74AUP1T45GF,132

Overview

The Nexperia 74AUP1T45GF,132 is a single-bit translating transceiver featuring bidirectional data transfer between ports A and B. It operates with dual supply voltages VCC(A) and VCC(B), both ranging from 1.1 V to 3.6 V. The device includes a direction control input (DIR) referenced to VCC(A). Schmitt trigger inputs ensure tolerance for slow signal transitions. It supports partial power-down via IOFF circuitry and suspend mode when supplies are at GND.

Feature Summary

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

Applications

• Interfacing low voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V
• Partial power-down applications requiring isolation of powered-down sections
• Systems requiring controlled unidirectional or bidirectional data flow

Procurement Notes

Verify the specific suffix GF indicates the XSON6 package type SOT886. Confirm the ordering code matches the required temperature range of -40 °C to +125 °C. Ensure compatibility with the target PCB footprint for the leadless package before finalizing procurement orders.

Selection Notes

Select this component when interfacing circuits operating at different logic levels within the 1.1 V to 3.6 V range. The DIR pin allows explicit control over data transmission direction. Consider the low static power consumption and high noise immunity for reliable operation in electrically noisy environments.

Part Context

This part belongs to the 74AUP family of advanced ultra-low power CMOS logic devices. It is designed for applications demanding minimal power dissipation while maintaining high-speed performance. The device integrates features suitable for portable electronics and battery-powered systems where power efficiency is critical.

Replacement Considerations

Direct substitutes include other variants of the 74AUP1T45 series with different package options, such as 74AUP1T45GW, 74AUP1T45GM, or 74AUP1T45GN, provided the package footprint is compatible.
