74AXP1T125GMH

Overview

The Nexperia 74AXP1T125GMH 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, which operates between 0.7 V and 2.75 V, while the output is referenced to VCCO, operating between 1.2 V and 5.5 V. This configuration enables voltage level translation. Schmitt-trigger action provides tolerance for slow input transitions. The device includes IOFF circuitry for partial power-down applications.

Feature Summary

• Dual supply architecture supporting independent input and output voltage domains
• Schmitt-trigger inputs ensure noise immunity and tolerance for slow rise/fall times
• IOFF circuitry prevents damaging backflow current during partial power-down states
• Low capacitance characteristics minimize dynamic power consumption

Applications

• Voltage level translation between low-voltage logic and higher-voltage peripherals
• Bus buffering in mixed-voltage system architectures
• Line driving for high-speed data transmission interfaces

Procurement Notes

Verify the specific suffix 'MH' against official Nexperia documentation, as standard listings typically utilize 'GM', 'GN', 'GS', or 'GX'. Confirm package type SOT886 matches project requirements. Ensure design accounts for the specified temperature range of -40 °C to +85 °C. Validate that input and output supply voltages remain within the defined operational limits to prevent device damage.

Selection Notes

Select this component when interfacing circuits with disparate supply voltages requiring robust signal integrity. The dual-supply design allows flexible voltage domain isolation. Consider the low input capacitance for high-frequency applications where signal loading must be minimized. Verify compatibility with system noise environments due to Schmitt-trigger input characteristics.

Part Context

This device belongs to the 74AXP series, designed for advanced low-power applications. It utilizes Nexperia's proprietary technology to achieve high speed with minimal power dissipation. The XSON6 package offers a compact footprint suitable for space-constrained designs. It serves as a specialized solution for modern embedded systems requiring efficient voltage translation.

Replacement Considerations

Standard equivalents include 74AXP1T125GM, 74AXP1T125GN, 74AXP1T125GS, and 74AXP1T125GX. These variants share identical electrical specifications but differ in package dimensions and thermal properties. Ensure pinout compatibility before substitution.
