74LVT125PW/AUJ

Overview

The NXP USA Inc. 74LVT125PW/AUJ 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, utilizing BiCMOS technology for high-speed performance and an output drive capability of +64 mA and -32 mA. The device includes bus hold data inputs to eliminate external pull-up resistors and IOFF circuitry for partial power-down applications. It supports live insertion and extraction without bus current loading when tied to a 5 V bus.

Feature Summary

• Features 3-state buffers with active LOW output enable inputs for precise control.
• Includes bus hold data inputs to maintain unused input states without external components.
• Provides IOFF circuitry to disable outputs and prevent backflow current during power-down.
• Supports live insertion and extraction while preventing bus current loading on 5 V buses.

Applications

• Partial power-down mode operation
• Live insertion and extraction systems
• Direct interface with TTL levels

Procurement Notes

Verify the specific package variant against the datasheet ordering information. Confirm that the AUJ suffix corresponds to the TSSOP14 plastic thin shrink small outline package (SOT402-1) as defined in the manufacturer's documentation. Ensure compatibility with the specified operating temperature range of -40 °C to +85 °C for the intended application environment.

Selection Notes

Select this component for designs requiring a 3.3 V quad buffer with high drive strength and 3-state control. The inclusion of bus hold inputs simplifies design by removing the need for external pull-up resistors. Verify that the system operates within the 2.7 V to 3.6 V supply voltage range and requires overvoltage tolerant inputs up to 5.5 V.

Part Context

This device belongs to the 74LVT/LVTH logic family, designed for 3.3 V applications. It serves as a buffer/line driver with 3-state outputs. The PW suffix indicates a TSSOP14 package. The product is manufactured by Nexperia, which acquired the semiconductor business previously associated with NXP.

Replacement Considerations

The 74LVTH125PW is a compatible alternative within the same series offering similar functionality and specifications.
