Texas Instruments SN74S189N is a high-speed, asynchronous static random-access memory (SRAM) component from the SN74S189 series. This TTL-compatible device features a memory organization of 16 words by 4 bits, providing a total capacity of 64 bits. It offers a maximum access time of 35ns, making it suitable for demanding applications. The output characteristics are 3-state, facilitating bus-oriented systems. Packaged in a 16-pin plastic dual in-line package (PDIP), the SN74S189N is designed for through-hole mounting with a terminal pitch of 2.54mm. This component finds application in various digital systems requiring fast, on-chip memory, including industrial control, telecommunications, and general-purpose computing. The operating temperature range is from 0°C to 70°C.
