Product Summary

The DM87S181J is a 1024 x 8-BIT TTL PROM. The schottky memories is organized in the popular 1024 words by 8 bits configuration. Memory enable inputs are enabled, the outputs represent the contents of the selected word. When disabled, the 8 outputs go to the "OFF" or high impedance state. PROM is shipped from the factory with lows in all lacations. A high may be programmed into any selected location by following the programming instructions.
