74xx125 74HC125 quad 3 state buffer integrated circuit demonstration for DIY electronics
Hello, guys. I am Rose. Today we will have a discussion about 74HC125. 74hc125 is a quad buffer/line driver. This article mainly introduce circuit, pinout, datasheet and other detailed information about Nexperia 74HC125.
74HC125D
The 74HC125 is a quad buffer/line driver with 3-state outputs which provides four independent buffer gates .
It is controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high impedance OFF-state. Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.The device is designed for operation with a power supply range of 2.0V to 6.0V.
