The Texas Instruments SN74LS189JP4 is a standard asynchronous SRAM with a memory organization of 16 words by 4 bits, providing a total density of 64 bits. This TTL-compatible component features an access time of 80 ns and 3-state outputs. Housed in a 16-lead ceramic dual in-line package (CDIP16) with through-hole termination, it operates within a supply voltage range of 4.5V to 5.5V, typically 5V. The SN74LS189 series is suitable for applications requiring high-speed data storage and retrieval, commonly found in industrial control systems and legacy data processing equipment. Its parallel interface facilitates straightforward integration into existing designs.
