  • Four Independent Non-Inverting Buffer Gates: The 74HC125 Quad Tri-state Buffer IC contains four independent gates, each performing a non-inverting buffer function. These gates provide a low impedance standard LS output with additional drive capability when enabled.
  • Enabled Mode: This IC operates in an enabled mode, ensuring fast switching times and standard TTL switching voltages.
  • Operating Temperature: Suitable for a wide range of conditions, with an operating temperature of up to 70°C.
  • Versatile Usage: Ideal for applications requiring signal buffering, multiplexers/demultiplexers, communications systems, and bus switching.
  • Three State Logic Outputs: Features three-state logic outputs for maximum flexibility and efficiency in your projects.

Quad Tri-state Buffer IC - 74HC125

The 74HC Series 74HC125 Quad tri state buffer IC contains four independent gates each of which performs a non-inverting buffer function. The outputs have the 3-STATE feature. When enabled, the outputs exhibit the low impedance characteristics of a standard LS output with additional drive capability to permit the driving of bus lines without external resistors.

The Quad tri state buffer IC 74HC125 is a great choice for those looking to extend the capabilities of their projects’ circuits. This integrated circuit allows you to use up to four separate, bi-directional data buses with independent control signals without increasing board space or power consumption. 

With its three state logic outputs, it ensures maximum flexibility and efficiency in each application that requires signal buffering such as multiplexers/demultiplexers communications systems and bus switching applications. In addition, this product has very low power dissipation making it ideal for battery-operated devices while keeping your final design compact at the same time!

This chip comes in an industry-standard 4-pin dual inline package (DIP) allowing easy integration into any project with minimal soldering needed on boards already designed using 5V CMOS technology standards. Furthermore, its wide operating temperature range capable of reaching up to -55°C (-67F), makes our tristate buffer the perfect solution when developing products for extreme climates such as freeze and require monitoring equipment outdoors or lab settings where extremely high temperatures are reached.

The combination of these two features along with durability make this tri state buffer IC suitable for most extreme working conditions applications perfectly replacing discrete components used before!

1.What is the function of the 74HC125 IC?

  • The 74HC125 is a quad buffer gate with three output states. It is frequently used in digital circuits to isolate and amplify signals, and it enables multiple devices to share the same data bus.

2.Can the 74HC125 IC be used for level-shifting applications? 

  • Yes, because it can operate at different voltage levels on the input and output sides, the 74HC125 IC can be used for level-shifting applications. When multiple devices must share the same bus, this prevents signal conflicts.
