MT5C6405 is a high-performance, low-power CMOS double-metal process SRAM chip that provides 12, 15, 20, 25, 35, 45, 55, and 70ns read and write speeds, and has a 2V battery backup function that can be used in industrial and military environments.
The MT5C6405 is a 16K × 4 static RAM employing a high‑speed, low‑power CMOS four‑transistor cell. It operates from a single +5 V supply and all inputs/outputs are TTL compatible. The device offers multiple access‑time options (12 ns to 70 ns) and is available in industrial, military and full‑military temperature ranges.
The datasheet provides detailed electrical characteristics, timing diagrams, mechanical dimensions, ordering information and cross‑reference part numbers for both ASI and SMD packages.
