While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q

outputs are latched at the logic levels set up at the D inputs.

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 the high-impedance state. In the high-impedance state, the outputs neither load nor drive the

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

without interface or pullup components.

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

while the outputs are in the high-impedance state.

outputs, preventing damaging current backflow through the devices when they are powered down.

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

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators

in a mixed 3.3-V/5-V system environment.
