74LVT125DB,118

Overview

The Nexperia 74LVT125DB,118 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW output enable inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes BiCMOS technology for high speed and drive capability. The device provides an output current capability of +64 mA and -32 mA. It includes bus hold data inputs to eliminate external pull-up resistors and IOFF circuitry for partial power-down applications. The component is housed in an SO14 plastic small outline package (SOT108-1) and is specified for operation from -40 °C to +85 °C.

Feature Summary

• BiCMOS high-speed performance with strong output drive capabilities
• Bus hold data inputs prevent undefined states without external components
• IOFF circuitry prevents damaging backflow current during power-down
• Overvoltage tolerant inputs allow direct interface with 5 V logic levels

Applications

• Bus-oriented architectures requiring 3-state buffering
• Clock distribution and buffering circuits
• Data acquisition systems
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's latest documentation to confirm packaging details and compliance status. Ensure that the SO14 package variant matches the design footprint requirements. Confirm availability through authorized distributors as production status may vary. Check for any recent product change notices regarding marking or assembly updates.

Selection Notes

Select this component when a 3.3 V logic family buffer with high drive strength is required. The 74LVT series is suitable for interfacing between 3.3 V devices and 5 V tolerant buses due to input overvoltage tolerance. Consider the SO14 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the Nexperia 74LVT logic family, which is designed for low-voltage applications. The 74LVT125 specifically functions as a quad buffer with 3-state outputs. It is distinct from the 74LVTH125 primarily in terms of internal transistor sizing and propagation delay characteristics, though they share similar pinouts and functional descriptions.

Replacement Considerations

The 74LVTH125D,118 is a related variant within the same datasheet offering similar functionality but potentially different dynamic characteristics.
