description/ordering information  
The ’AHC573 devices are octal transparent  
D-type latches designed for 2-V to 5.5-V V  
operation.  
CC  
When the latch-enable (LE) input is high, the  
Q outputs follow the data (D) inputs. When LE is  
low, the Q outputs are latched at the logic levels  
of the D inputs.  
GND 10

SN54AHC573 . . . FK PACKAGE  
(TOP VIEW)  
A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal logic  
state (high or low) 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.

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.
