74AUP1T98GW,125

Overview

The Nexperia 74AUP1T98GW,125 is a low-power configurable gate with voltage-level translator housed in a 6-TSSOP package. It operates on a supply voltage (VCC) of 2.3 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs and IOFF circuitry for partial power-down applications. It provides unidirectional level translation between A-side logic levels (1.8 V to 2.7 V) and B-side logic levels (2.3 V to 3.6 V).

Feature Summary

• Configurable multiple function gate capable of implementing MUX, AND, OR, NAND, NOR, inverter, and buffer functions via 3-bit input selection.
• Integrated voltage-level translator enabling direct interfacing between different logic voltage domains without external components.
• Schmitt-trigger inputs provide high noise immunity and tolerance for slower input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent potentially damaging backflow currents.

Applications

• Partial power-down mode operation in portable electronic devices.
• Interfacing circuits operating at different logic voltage levels.
• Signal buffering and inversion in low-power digital systems.
• Implementation of configurable logic functions in space-constrained designs.

Selection Notes

Select this component when a single IC must perform multiple logic functions while simultaneously translating signal voltages between two distinct domains. Ensure the application requires unidirectional data flow from the A-side inputs to the B-side output. Confirm that the system voltage ranges align with the specified VCCA and VCCB limits to maintain proper logic threshold performance.

Part Context

This device belongs to the Nexperia 74AUP series, which utilizes advanced CMOS technology for low power consumption and high-speed operation. The 74AUP1T98 specifically combines configurable logic capabilities with integrated level shifting, distinguishing it from standard logic gates or dedicated translators. It is designed for applications requiring flexible logic implementation within strict power and size constraints.

Replacement Considerations

Direct replacements require matching the 6-TSSOP package, 2.3 V to 3.6 V supply range, and configurable gate functionality with level translation. Verify pinout compatibility and ensure the substitute supports the required IOFF power-down feature if partial power-down operation is critical to the design.

FAQ

How are the logic functions configured?

The logic function is selected by connecting the three data inputs (A, B, and C) directly to VCC or GND according to the function selection table provided in the datasheet.

What is the purpose of the IOFF circuitry?

The IOFF circuitry disables the output when the device is powered down (VCC = 0 V), preventing damaging backflow current through the device when connected to live buses.

Can this device translate signals bidirectionally?

No, the 74AUP1T98 is a unidirectional device. Data flows from the A-side inputs (configured for lower voltage levels) to the B-side output (compatible with higher voltage levels).
