74AXP1T125GSH

Overview

The Nexperia 74AXP1T125GSH is a dual supply non-inverting buffer/line driver with 3-state output. It features one input (A), an output (Y), and an output enable input (OE). The input supply voltage (VCCI) ranges from 0.7 V to 2.75 V, while the output supply voltage (VCCO) ranges from 1.2 V to 5.5 V. This configuration enables voltage level translation between different logic families. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down applications.

Feature Summary

• Dual supply architecture allowing independent input and output voltage domains for level translation
• Schmitt-trigger action at all inputs provides tolerance for slower rise and fall times
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents
• Low static and dynamic power consumption across the entire supply range

Applications

• Voltage level translation between low-voltage and standard logic interfaces
• Partial power-down mode operation in multi-supply systems
• Signal buffering where high noise immunity is required
• Line driving applications requiring 3-state control

Procurement Notes

Verify the specific package suffix against the ordering information table to ensure correct physical dimensions and terminal count. Confirm that the requested variant matches the required temperature range and marking code specifications. Cross-reference the datasheet revision date to ensure compliance with current product specifications before finalizing procurement orders.

Selection Notes

Select this component when interfacing circuits operating at distinct voltage levels, specifically where the input domain is below 2.75 V and the output domain extends up to 5.5 V. Ensure the application requires a single-channel buffer with 3-state capability. Verify that the low input capacitance and high noise immunity meet the signal integrity requirements of the target design.

Part Context

This device belongs to the AXP family of Si-gate CMOS devices designed for ultra-low power consumption. It is part of a series of dual-supply buffers and translators manufactured by Nexperia. The family supports various small outline packages suitable for space-constrained surface-mount applications.

Replacement Considerations

Direct substitutes include other variants within the 74AXP1T125 series such as 74AXP1T125GM, 74AXP1T125GN, or 74AXP1T125GX, provided the package type matches the board layout requirements.
