Texas Instruments SNC54LS189AJ is a standard asynchronous SRAM device offering a 16 x 4 memory organization. This TTL-compatible component features a maximum access time of 90ns and a 3-state output characteristic. Housed in a 16-lead ceramic DIP package (JESD30 code R-XDIP-T16), it operates over a temperature range of -55°C to 125°C. The SNC54LS189AJ is suitable for applications requiring robust memory solutions, including industrial automation and defense systems. Its MIL-STD-883 Class B (Modified) screening level indicates its suitability for demanding environments. The component operates with a nominal supply voltage of 5V, with a range of 4.5V to 5.5V. The through-hole mounting terminal form and 2.54mm terminal pitch are standard for this package type.
