DM9334
8-Bit Addressable Latch
General Description
The DM9334 is a high speed 8-bit Addressable Latch
designed for general purpose storage applications in digital
systems. It is a multifunctional device capable of storing
single line data in eight addressable latches, and being a
one-of-eight decoder and demultiplexer with active level
HIGH outputs. The device also incorporates an active level
LOW common clear for resetting all latches, as well as an
active level LOW enable.
The DM9334 has four modes of operation which are shown
in the mode selection table. In the addressable latch mode,
data on the data line (D) is written into the addressed latch.
The addressed latch will follow 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 will follow the state of the D input with all
other inputs in the LOW state. In the clear mode all outputs
are LOW and unaffected by the address and data inputs.
When operating the device 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.
The function tables summarize the operation of the prod-
uct.
