DESCRIPTION:
The CBTLV3125 features four independent switches. Each switch is
enabled when the associated output-enable (OE) input is low.
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.
