High–Performance Silicon–Gate CMOS

The MC54/74HC259A is identical in pinout to the LS259. The device  
inputs are compatible with standard CMOS outputs; with pullup resistors,  
they are compatible with LSTTL outputs.

N SUFFIX  
PLASTIC PACKAGE  
CASE 648–08  
The HC259A has four modes of operation as shown in the mode selection  
table. In the addressable latch mode, the data on Data In is written into the  
addressed latch. The addressed latch follows the data input with all  
non–addressed latches remaining in their previous states. In the memory  
mode, all latches remain in their previous state and are unaffected by the  
Data or Address inputs. In the one–of–eight decoding or demultiplexing  
mode, the addressed output follows the state of Data In with all other outputs  
in the LOW state. In the Reset mode all outputs are LOW and unaffected by  
the address and data inputs. When operating the HC259A as an  
addressable latch, changing more than one bit of the address could impose  
a transient wrong address. Therefore, this should only be done while in the  
memory mode.
