Description  
• Buffered Inputs and Outputs  
• Four Operating Modes  
• Typical Propagation Delay of 15ns at V  
The ’HC259 and ’HCT259 Addressable Latch features the  
low-power consumption associated with CMOS circuitry and  
has speeds comparable to low-power Schottky.

This latches three active modes and one reset mode. When  
both the Latch Enable (LE) and Master Reset (MR) inputs are  
low (8-line Demultiplexer mode) the output of the addressed  
latch follows the Data input and all other outputs are forced  
low. When both MR and LE are high (Memory Mode), all  
outputs are isolated from the Data input, i.e., all latches hold

high. A condition of LE low and MR high (Addressable Latch  
mode) allows the addressed latch’s output to follow the data  
input; all other latches are unaffected. The Reset mode (all  
outputs low) results when LE is high and MR is low.
