description/ordering information  
The ’AC533 devices are octal transparent D-type  
latches with 3-state outputs. When the  
latch-enable (LE) input is high, the Q outputs  
follow the complements of the data (D) inputs.  
When LE is taken low, the Q outputs are latched  
at the inverse 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 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.  
To ensure the high-impedance state during power up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
