74ABT125DB,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT125DB,112 is a quad buffer and line driver manufactured by Nexperia (NXP USA Inc.) in an SO14 plastic small outline package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features BiCMOS technology for high-speed performance and provides output drive capabilities of HIGH -32 mA and LOW +64 mA. It includes IOFF circuitry for partial power-down applications and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Quad bus interface with 3-state outputs controlled by active LOW enable inputs.
• IOFF circuitry prevents damaging backflow current during partial power-down states.
• Direct interface compatibility with TTL logic levels.
• Power-up 3-state functionality ensures safe initialization.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down system architectures requiring isolation.
• High-speed data bus buffering and line driving.
• Live insertion and extraction signal routing.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the exact package type and temperature grade. Confirm that the component status aligns with current production schedules, as availability may vary by region. Ensure compliance with RoHS directives relevant to the target market before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad non-inverting buffer with 3-state control is required for 5V logic systems. The BiCMOS technology offers superior speed compared to standard CMOS alternatives. Consider the SO14 package dimensions if board space constraints allow for standard small outline footprints rather than shrink or flat packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, which utilizes BiCMOS technology to achieve high switching speeds while maintaining low power consumption. The 74ABT125 specifically functions as a quad buffer, providing signal integrity improvements for digital communication lines. It is distinct from the 74LVC or 74HC families due to its specific voltage range and drive strength characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes such as the 74ABT125PW or 74ABT125BQ if different packaging is required. Verify pinout compatibility and electrical specifications against alternative manufacturers' offerings to ensure functional equivalence without redesigning the PCB layout.
