1024 x 1-Bit Monolithic High-Speed TTL Bipolar Random-Access Memory (RAM) IC, featuring an ultra-fast 35-nanosecond random address access time index. Operating across a standard 5V logic supply rail, it integrates a high-density full-static memory cell matrix binned to eliminate system wait states, propagate jitter-free data caching, and handle active microinstruction storage buffers inside legacy mainframe architectures and automated instrumentation backplanes, housed in an industry-standard 16-pin through-hole plastic or ceramic dual in-line package (DIP-16) layout. Originally manufactured by Harris Semiconductor. Show more
