These octal latches are designed specifically for low-voltage (3.3-V) V

operation, but with the capability to  
CC  
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 a 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 need for 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.  
When V is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
through a pullup resistor;  
CC  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
