74LVTH125BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVTH125BQ,115 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 for low-level states and -32 mA for high-level states. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with TTL levels. Bus hold data inputs eliminate the need for external pull-up resistors. The component includes IOFF circuitry for partial power-down applications and complies with JEDEC standard JESD8C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features BiCMOS technology for high-speed operation and robust output drive capabilities.
• Includes bus hold data inputs to maintain unused input states without external components.
• Supports live insertion and extraction while preventing bus current loading on 5 V buses.
• Provides IOFF circuitry to disable outputs and prevent damaging backflow currents during partial power-down.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operations requiring isolation of powered-down sections.
• Bus interface buffering where direct TTL level interfacing is required.
• Systems permitting live insertion and extraction of bus segments.
• High-speed signal transmission lines requiring strong drive currents.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN14 package (SOT762-1) as indicated in the datasheet. Confirm that the application environment remains within the specified temperature range of -40 °C to +85 °C. Ensure input voltages do not exceed the absolute maximum ratings to prevent damage. Check for compliance with relevant RoHS directives if applicable to your manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-state control is needed for 3.3 V logic systems. It is suitable for applications requiring direct interfacing with 5 V TTL devices due to its overvoltage tolerant inputs. Consider this part for designs needing bus hold functionality to simplify schematic design by removing external pull-up resistors. Verify that the DHVQFN14 package fits the available PCB footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LVTH series, which utilizes BiCMOS technology to achieve high speed and strong drive capabilities within a 3.3 V supply domain. It is functionally similar to the 74LVT125 but offers enhanced performance characteristics typical of the LVTH family. The BQ suffix denotes the specific DHVQFN14 leadless package variant manufactured by Nexperia.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74LVT125BQ,115 is the non-H (standard LVT) equivalent within the same package. Other variants in the 74LVT125 family include SO14 (74LVT125D) and TSSOP14 (74LVT125PW) packages, though these require different footprints.
