SN74HC125

具有三态输出翻两番总线缓冲器GATES QUADRUPLE BUS BUFFER GATES WITH 3-STATE OUTPUTS

The SNx4HC125 device is a quadruple set of bus buffer gates and features independent line drivers with 3-state outputs. The SNx4HC125 is designed for 2-V to 6-V VCC operation. 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.
