Texas Instruments SN54LS189AW is a 64-bit (16 words x 4 bits) standard asynchronous SRAM. Featuring a maximum access time of 90ns, this TTL-compatible device operates across a wide temperature range of -55°C to +125°C. The SN54LS189AW utilizes a 16-pin ceramic flat pack (CDFP16) with a 1.27mm terminal pitch, designed for surface mounting. Its output characteristics include 3-state functionality, enabling efficient bus sharing. This component is suitable for applications in aerospace and defense, and industrial automation. The device operates from a nominal supply voltage of 5V, with a range of 4.5V to 5.5V. This part is screened to MIL-STD-883 Class B (Modified) standards.
