The Texas Instruments SNJ54LS189AJ is a 64-bit (16 words x 4 bits) asynchronous Random Access Memory (RAM) featuring TTL compatibility. This standard SRAM offers a maximum access time of 90ns and operates with a 5V supply, ranging from 4.5V to 5.5V. The device provides 3-state outputs for flexible bus interfacing and is housed in a 16-lead ceramic dual in-line package (CDIP16) with through-hole mounting. Designed for rigorous environments, it operates across an extended temperature range of -55°C to 125°C and adheres to military screening standards, including 883B. The SNJ54LS189AJ is suitable for applications demanding high reliability in aerospace, defense, and industrial control systems.
