The Texas Instruments SMJ61CD256-55JDM is a 256K x 1 CMOS standard SRAM with a maximum access time of 55ns. This asynchronous memory device features separate input/output, 3-state output characteristics, and an automatic power-down function. Operating from a supply voltage range of 4.5V to 5.5V, it is designed for applications requiring robust performance across a wide temperature spectrum, from -55°C to +125°C. The component is housed in a 24-lead ceramic dual in-line package (CDIP24), suitable for through-hole mounting. This SRAM is often specified for demanding environments within aerospace, defense, and industrial sectors where reliability and extended temperature operation are critical. Its organization and specifications align with traditional memory architectures requiring high-speed access and dependable data retention.
