74ABT125PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT125PW,112 is a quad buffer and line driver featuring three-state outputs controlled by active LOW output enable inputs (nOE). It utilizes BiCMOS technology to provide high-speed performance and robust output drive capabilities within a supply voltage range of 4.5 V to 5.5 V. The device incorporates IOFF circuitry to support partial power-down applications by preventing damaging backflow currents when the device is powered down. It ensures direct interface compatibility with TTL levels and includes latch-up protection exceeding 500 mA per JESD78B class II level A.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS technology enables high-speed operation and strong output drive capability for reliable signal transmission.
• Integrated IOFF circuitry prevents potentially damaging backflow currents during partial power-down scenarios.
• Outputs assume a high-impedance OFF-state when the nOE input is HIGH, allowing live insertion and extraction.
• Inputs are disabled during the three-state mode to ensure stable bus operations.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down system architectures requiring isolation of powered-down components
• Quad bus interface designs utilizing three-state buffering
• Mixed voltage environments interfacing directly with TTL logic levels

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring four independent buffers with three-state control in a single package. Ensure the application operates within the specified 4.5 V to 5.5 V supply range. Consider the TSSOP14 package dimensions if board space is constrained. Verify that the load capacitance and resistance values align with the dynamic characteristics defined in the datasheet for the required propagation delays.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series, which represents Advanced BiCMOS Technology from Nexperia. This family combines the speed of bipolar transistors with the low power consumption of CMOS. The 74ABT125 specifically provides non-inverting buffering with three-state outputs, distinguishing it from standard inverters or non-three-state drivers within the broader logic portfolio.
