Data flow from  
A to Y is controlled by the  
output-enable (OE) input. The device operates in the  
transparent mode when the latch-enable (LE) input is  
high. The A data is latched if the clock (CLK) input is  
held at a high or low logic level. If LE is low, the A  
data is stored in the latch/flip-flop on the low-to-high  
transition of CLK. When OE is high, the outputs are in  
the high-impedance state.

To ensure the high-impedance state during power up  
or power down, OE should be tied to VCC through a  
pullup resistor; the minimum value of the resistor is  
determined by the current-sinking capability of the  
driver.  
LE  
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.
