Texas Instruments SNJ54LS189W is a 64-bit (16 words x 4 bits) asynchronous SRAM with a maximum access time of 90ns. This TTL-compatible memory component features a 16x4 memory organization with 3-state outputs. Designed for robust operation, it offers a wide operating temperature range from -55°C to 125°C and operates from a 4.5V to 5.5V supply. The component is housed in a 16-lead ceramic flatpack (CDFP16) with a terminal pitch of 1.270mm, suitable for surface mounting. Screening levels comply with 38535Q/M, 38534H, and 883B standards. This SRAM is utilized in aerospace and defense applications requiring high reliability.
