9334 General Description
The DM9334 is a high speed 8-bit Addressable Latch designed for general purpose storage applications in digitalsystems. It is a multifunctional device capable of storing single line data in eight addressable latches, and being a oneof- 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 nonaddressed 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 product.

9334 Maximum Ratings
If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
Supply Voltage 7V
Input Voltage 5.5V
Operating Free Air Temperature Range
Military -55 to +125
Commercial 0 to +70
Storage Temperature Range -65 to +150
Note: The ``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed.
The device should not be operated at these limits. The parametric values defined in the ``Electrical Characteristics'' table are not guaranteed at the absolute maximum ratings. The ``Recommended Operating Conditions'' table will define the conditions for actual device operation.
