The Texas Instruments SN74LS189AJ is a 16 × 4 bit asynchronous static random-access memory (SRAM) from the SN74LS189 series. This TTL-compatible device offers a maximum access time of 80ns and features a 3-state output characteristic. Designed for through-hole mounting, it is housed in a 16-lead ceramic dual in-line package (CDIP16), conforming to the R-XDIP-T16 JESD-30 code. Operating within a supply voltage range of 4.5V to 5.5V, with a nominal 5V, this memory component is suitable for applications requiring fast data storage and retrieval in industrial and consumer electronics. Its 64-bit memory density and parallel interface make it a foundational element for various embedded systems.
