The Texas Instruments SMJ68CE256-55JDM is a standard SRAM component organized as 32K words by 8 bits, providing a memory density of 262,144 bits. This CMOS device features an asynchronous operating mode with a maximum access time of 55 ns. The SMJ68CE256 series component operates within a supply voltage range of 4.5V to 5.5V and exhibits an automatic power-down feature to minimize standby current, which is rated at a maximum of 0.0002A.
Designed for demanding applications, this component is housed in a 28-terminal ceramic dual in-line package (CDIP28) suitable for through-hole mounting. It operates across a wide temperature range from -55°C to +125°C, meeting rigorous screening standards such as 883B. The SMJ68CE256-55JDM is well-suited for use in aerospace, defense, and industrial control systems where high reliability and robust performance are critical.
