74HC125PW集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

1. General description

The 74HC125; 74HCT125 is a quad buffer/line driver with 3-state outputs 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.
