description/ordering information (continued)

The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-

Ω series resistors

to reduce overshoot and undershoot.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors

with the bus-hold circuitry is not recommended.

the minimum value of the resistor is determined by the current-sinking capability of the driver.

disables the outputs, preventing damaging current backflow through the device when it is powered down. The

power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,

which prevents driver conflict.
