The Texas Instruments SMJ64C256-55JDM is a 65,536-word by 4-bit (64K x 4) CMOS standard static RAM designed for high-reliability applications. This asynchronous memory device features a maximum access time of 55 nanoseconds and operates from a nominal supply voltage of 5V, with a range of 4.5V to 5.5V. The SMJ64C256 series incorporates an automatic power-down feature to reduce standby current consumption. Its 24-pin ceramic dual-in-line package (CDIP24, R-CDIP-T24) with through-hole terminals ensures robust integration into demanding system architectures. This component is suitable for use in aerospace, defense, and industrial systems requiring dependable memory performance under extended temperature ranges, from -55°C to +125°C. The SMJ64C256-55JDM adheres to MIL-STD-883 Class B (Modified) screening standards.
