74HC125 DIP IC Quad Bus Buffer With 3 State Outputs (74HC125 IC)

The 74HC125 is a quad bus buffer integrated circuit designed for signal buffering and data line isolation in digital electronic systems. It contains four independent buffer gates with three state outputs allowing controlled data transfer on shared digital buses.

This IC belongs to the high speed CMOS logic family and provides reliable switching performance with low power consumption. Each buffer includes an output enable control that allows the output to be enabled or placed in a high impedance state making the device suitable for bus oriented digital systems microprocessor interfacing and signal isolation circuits. The DIP package allows easy integration into breadboard prototypes and PCB based circuit designs.
