Description  
• Buffered Inputs and Outputs  
• Four Operating Modes  
• Typical Propagation Delay of 15ns at V  
The Harris CD74HC259 and CD74HCT259 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

• Wide Operating Temperature Range . . . -55 C to 125 C outputs are isolated from the Data input, i.e., all latches hold  
the last data presented before the LE transition from low to  
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.
