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
