74ABT125BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT125BQ,115 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW output enable inputs. It utilizes BiCMOS technology to provide high-speed performance and robust drive capability within a supply voltage range of 4.5 V to 5.5 V. The device supports direct interfacing with TTL levels and includes IOFF circuitry for partial power-down applications. It operates reliably across an ambient temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS technology enables high-speed operation and strong output drive capabilities.
• Integrated IOFF circuitry prevents damaging backflow currents during partial power-down states.
• Outputs assume a high-impedance OFF-state when the output enable input is HIGH.
• Provides live insertion and extraction support through defined 3-state functionality.
