74ABT125PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT125PW,118 is a quad buffer and line driver featuring BiCMOS technology for high-speed operation. It operates within a supply voltage range of 4.5 V to 5.5 V and provides TTL-compatible direct interfacing. The device includes four non-inverting buffers with independent active-LOW output enable inputs (nOE). Outputs assume a high-impedance OFF-state when nOE is HIGH. It supports partial power-down applications via IOFF circuitry and permits live insertion and extraction.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS technology enables high-speed performance and robust output drive capabilities.
• IOFF circuitry prevents damaging backflow current during partial power-down conditions.
• Outputs automatically assume a high-impedance state upon power-up.
• Inputs are disabled during the 3-state mode to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature range specification aligns with application requirements. Ensure the specific revision level meets design constraints. Cross-reference the manufacturer's latest documentation for any updates to pinning or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with strong drive capability in a 5 V environment. The TSSOP14 package offers a compact solution for surface-mount applications. Consider the propagation delay specifications if timing margins are tight. Verify that the load capacitance and resistance values remain within the recommended operating conditions for optimal switching performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, which utilizes BiCMOS technology to achieve higher speeds compared to standard CMOS counterparts. It serves as a quad buffer/line driver variant within the broader 74-series ecosystem. The PW suffix specifically denotes the TSSOP14 plastic thin shrink small outline package configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT126D is a compatible alternative offering similar functionality but with an active-LOW output enable input polarity opposite to the 74ABT125.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down scenarios?

The integrated IOFF circuitry disables the outputs to prevent potentially damaging backflow current through the device when it is powered down.

What is the behavior of the outputs during power-up?

The device features power-up 3-state functionality, causing the outputs to assume a high-impedance OFF-state immediately upon power-up.
