description/ordering information  
The ’AHC373 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.  
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.
