10.3. Pullup or pulldown resistors on I/O lines

The device is designed to drive capacitive loads up to 70 pF. The device's output drivers have a low DC drive

strength. Pullup and pulldown resistors that are externally linked to the data I/Os must have values greater than

50 kΩ in order to avoid interfering with the device's output drivers.

For the same reason, the device must not be used in applications like 1-Wire or I2C where an open-drain driver

is connected on the bidirectional data I/O.

10.4. Device functional modes

There are two functional modes for the device: enabled and disabled. The device can be enabled by setting the

OE input high. To disable the device, set the OE input low, which places all I/Os in a high impedance state.
