Product Introduction

Overview

The SN74ABT125, produced by Texas Instruments, is a quadruple bus buffer gate with 3-state outputs. This device is designed to operate in a wide range of applications, including hot-insertion scenarios, due to its Ioff and power-up 3-state capabilities. The SN74ABT125 supports independent line drivers, each with 3-state outputs, which can be placed in a high-impedance state during power-up and power-down to prevent driver conflicts. This feature is particularly useful in systems where multiple devices need to share the same bus.

Key Features

  • Independent line drivers with 3-state outputs, allowing for high-impedance state during power-up and power-down to prevent driver conflicts.
  • Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
  • Supports hot-insertion applications.
  • Wide operating temperature range from -55°C to 125°C.
  • High-level output current capability up to -32 mA and low-level output current capability up to 64 mA.
  • Input transition rise or fall rate of 10 ns/V.

Applications

  • Hot-insertion applications where devices need to be added or removed without powering down the system.
  • Bus systems where multiple devices share the same bus and need to be isolated during power cycles.
  • Industrial and automotive systems requiring robust and reliable bus buffering.
  • Personal computers and other electronic devices that require stable and controlled bus operations.
