description/ordering information (continued)

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high

or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive

the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus

lines without interface or pullup components.

OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while

the outputs are in the high-impedance state.

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.
