74LVT125D,118

Overview

The Nexperia 74LVT125D,118 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW output enable inputs (nOE). It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides an output capability of +64 mA and -32 mA. It includes bus hold data inputs to eliminate external pull-up resistors for unused inputs. The component supports partial power-down applications via IOFF circuitry, which disables the output to prevent damaging backflow current. It is housed in an SO14 plastic small outline package.

Feature Summary

• Features overvoltage tolerant inputs capable of handling up to 5.5 V while operating at lower supply voltages.
• Includes IOFF circuitry that enables partial power-down mode operation by disabling outputs during power-off states.
• Incorporates bus hold data inputs to maintain defined logic levels on unused pins without requiring external components.

Applications

• Partial power-down systems requiring protection against backflow current
• Bus interface buffering with 3-state control
• Live insertion and extraction scenarios

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVT125 family includes variants such as PW and BQ. Confirm the revision history aligns with current manufacturing standards. Ensure compliance with RoHS directives and check for any recent product change notices regarding marking or assembly updates before finalizing procurement specifications.

Selection Notes

Select this component when a 3.3 V quad buffer with high drive capability is required. It is suitable for interfaces directly connecting to TTL levels. Consider the 74LVTH125 variant if higher speed performance is needed compared to the standard LVT series. Ensure the application environment stays within the specified temperature range of -40 °C to +85 °C.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as a buffer and line driver within Nexperia's portfolio of digital logic integrated circuits. The device is manufactured using BiCMOS technology to achieve high speed and strong output drive characteristics suitable for demanding bus interface applications.

Replacement Considerations

The 74LVTH125D,118 is a documented substitute offering similar functionality with potentially different dynamic characteristics. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
