Description

This DM74S473 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 DM74S473 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.
