SEMICONDUCTOR TECHNICAL DATA

J SUFFIX

CERAMIC PACKAGE

CASE 620–10

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.
