5 Description (continued)
The V
CC
isolation feature ensures that if either V
CC
input is at GND, then both ports are in the high-impedance
state. The bus-hold circuitry on the powered-up side always stays active.
Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state. Use of pull-up or pull-down
resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry on the powered-up side always
stays active.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pull-up
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
