74LVT125BQ,115

Overview

The Nexperia 74LVT125BQ,115 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW enable inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes BiCMOS technology for high-speed performance. The device provides an output drive capability of +64 mA and -32 mA. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with TTL levels. It includes bus hold data inputs to eliminate external pull-up resistors and IOFF circuitry for partial power-down applications.

Feature Summary

• BiCMOS high-speed technology with strong output drive capabilities
• Overvoltage tolerant inputs compatible with 5.5 V signals
• Bus hold inputs prevent undefined states without external components
• IOFF circuitry prevents backflow current during partial power-down

Applications

• Bus interface buffering
• Partial power-down system management
• TTL level translation and interfacing

Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN14 package (SOT762-1) as listed in the official Nexperia documentation. Confirm that the required temperature range matches the specified -40 °C to +85 °C operational limits. Ensure design compatibility with the 2.7 V to 3.6 V supply voltage constraints before procurement.

Selection Notes

Select this component when a quad buffer with 3-state control is required for 3.3 V systems. It is suitable for applications needing direct TTL interfacing due to input tolerance. Consider the DHVQFN14 package for space-constrained PCB layouts. Verify that the load conditions do not exceed the specified output current limits of 64 mA and -32 mA.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It is functionally similar to the 74LVTH125 but distinguished by its specific manufacturing variant. The BQ suffix indicates the DHVQFN14 leadless package, differentiating it from SO or TSSOP variants within the same logical family.

Replacement Considerations

The 74LVTH125BQ,115 is the primary equivalent within the same datasheet. Other packages such as 74LVT125D or 74LVT125PW offer identical electrical functionality but differ in physical footprint.
