Texas Instruments SNC54LS189AW is a 64-bit static random-access memory (SRAM) organized as 16 words by 4 bits. This asynchronous SRAM features a maximum access time of 90ns and operates with TTL technology. The device is housed in a 16-terminal Ceramic FlatPack (CDFP16) with a rectangular shape and dual-position flat terminals on a 1.270mm pitch. Designed for extended temperature operation from -55°C to 125°C, it requires a supply voltage between 4.5V and 5.5V. The SNC54LS189AW offers 3-state output characteristics and is suitable for applications requiring high reliability, including military and aerospace systems. The memory IC type is Standard SRAM with a memory density of 64 bits.
