74AUP1T34GZYL

Overview

The Nexperia 74AUP1T34GZYL is a single-channel translating buffer in an XSON-5 package (SOT8065). It operates with dual supply voltages VCC(A) and VCC(Y), both ranging from 1.1 V to 3.6 V. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down applications. Static supply current is typically 0.9 µA at 25 °C, rising to 1.4 µA at +125 °C. Propagation delay ranges from approximately 2 ns to 33 ns depending on load capacitance and voltage levels.

Feature Summary

• Dual-supply architecture allowing independent voltage domains for input and output ports
• Schmitt-trigger action provides tolerance for slow input rise and fall times
• IOFF circuitry disables outputs to prevent damaging backflow currents during power-down

Applications

• Connecting logic circuits operating at different voltage levels
• Partial power-down mode systems requiring isolation of powered-down ports
• Interfaces requiring high noise immunity with slow signal transitions

Procurement Notes

Verify the specific ordering suffix GZYL corresponds to the XSON-5 package variant SOT8065-1 with side-wettable flanks. Confirm that the component meets RoHS compliance standards as specified in the product data sheet. Ensure the procurement source provides valid traceability documentation for this Nexperia part number.

Selection Notes

Select this component when a single-channel unidirectional buffer is required between two distinct voltage domains within the 1.1 V to 3.6 V range. The XSON-5 package is suitable for space-constrained designs. Consider the propagation delay variations across different load capacitances and temperature ranges when designing timing-critical interfaces.

Part Context

This device belongs to the 74AUP series of low-power CMOS logic ICs manufactured by Nexperia. The 74AUP1T34 specifically functions as a translating buffer, enabling communication between digital subsystems running at different supply voltages while maintaining signal integrity through Schmitt-trigger inputs.

Replacement Considerations

Direct pin-compatible replacements include other variants of the 74AUP1T34 family such as 74AUP1T34GW or 74AUP1T34GM, provided the package type matches the design requirements.
