MM74HC259  
8-Bit Addressable Latch/3-to-8 Line Decoder  
inputs. To eliminate the possibility of entering erroneous  
data into the latches, the enable should be held HIGH  
(inactive) while the address lines are changing.  
General Description  
The MM74HC259 device utilizes advanced silicon-gate  
CMOS technology to implement an 8-bit addressable latch,  
designed for general purpose storage applications in digital  
systems.  
If enable is held HIGH and CLEAR is taken LOW all eight  
latches are cleared to a LOW state. If enable is LOW all  
latches except the addressed latch will be cleared. The  
addressed latch will instead follow the D input, effectively  
implementing a 3-to-8 line decoder.  
The MM74HC259 has a single data input (D), 8 latch out-  
puts (Q1–Q8), 3 address inputs (A, B, and C), a common  
enable input (G), and a common CLEAR input. To operate  
this device as an addressable latch, data is held on the D  
input, and the address of the latch into which the data is to  
be entered is held on the A, B, and C inputs. When  
ENABLE is taken LOW the data flows through to the  
addressed output. The data is stored when ENABLE transi-  
tions from LOW-to-HIGH. All unaddressed latches will  
remain unaffected. With enable in the HIGH state the  
device is deselected, and all latches remain in their previ-  
ous state, unaffected by changes on the data or address  
All inputs are protected from damage due to static dis-  
charge by diodes to VCC and ground.  
Features  
■ Typical propagation delay: 18 ns  
■ Wide supply range: 2–6V  
■ Low input current: 1 µA maximum  
■ Low quiescent current: 80 µA maximum (74HC Series)
