General Description
This Schottky memory is organized in the popular 512
words by 8 bits configuration. A memory enable input is provided to control the output states. When the device is enabled, the outputs represent the contents of the selected

impedance state.
PROMs are shipped from the factory with lows in all locations. A high may be programmed into any selected location
by following the programming instructions.
