74AXP1T125GWH

Overview

The Nexperia 74AXP1T125GWH is a dual supply non-inverting buffer/line driver with 3-state output. It features one input (A), an output (Y), an output enable input (OE) and dual supply pins (VCCI and VCCO). The inputs are referenced to VCCI and the output is referenced to VCCO. All inputs can be connected directly to VCCI or GND. VCCI can be supplied at any voltage between 0.7 V and 2.75 V and VCCO can be supplied at any voltage between 1.2 V and 5.5 V.

Feature Summary

• Provides voltage level translation capabilities by separating input and output supply domains.
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current during partial power-down applications.
• Schmitt-trigger action at all inputs ensures tolerance of slower input rise and fall times.

Applications

• Voltage level translation between different logic families
• Partial power-down mode operation in multi-supply systems
• Bus buffering for high-speed data lines

Procurement Notes

Verify the specific package suffix against the ordering information table, as the 'GWH' designation corresponds to the XSON6 SOT1115 package variant. Confirm that the component status remains active, as Nexperia periodically updates product longevity and availability through official notifications. Ensure the design accounts for the specified thermal derating characteristics associated with this particular package type.

Selection Notes

Select this device when interfacing circuits operating at distinct voltage levels, specifically where the input domain ranges from 0.7 V to 2.75 V and the output domain requires 1.2 V to 5.5 V. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transition rates. Consider the low static power consumption and ESD protection ratings for sensitive portable or automotive applications.

Part Context

This component belongs to the AXP series of Si-gate CMOS devices designed for ultra-low power consumption. Unlike standard single-supply buffers, the AXP family utilizes dual supply rails to facilitate seamless voltage translation without external components. The 74AXP1T125GWH represents a specific packaging option within this functional family, optimized for space-constrained printed circuit board layouts.

Replacement Considerations

Direct replacements include other variants within the 74AXP1T125 family such as 74AXP1T125GM (SOT886), 74AXP1T125GS (SOT1202), and 74AXP1T125GX (SOT1255-2). These alternatives share identical electrical specifications but differ in physical package dimensions and thermal properties. Verify pinout compatibility before substitution.
