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
word. When disabled, the 8 outputs go to the ‘‘OFF’’ or high
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.
