SN74HCT125数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

These bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\\ input is high.

To ensure the high-impedance state during power up or power down, OE\\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
