Texas Instruments SMJ27C256-120JM is a 32768 x 8 bit CMOS UV Erasable Programmable Read-Only Memory (UVPROM) with a maximum access time of 120ns. This device offers a memory density of 262,144 bits and operates asynchronously. Designed for robust performance across a wide temperature range from -55°C to +125°C, it features 3-state outputs and a common I/O configuration. The SMJ27C256 series component is housed in a 28-lead Ceramic Dual In-line Package (CDIP28) with through-hole termination, suitable for applications requiring high reliability and radiation hardening, often found in aerospace and military systems. It operates from a nominal 5V supply voltage with typical standby and active supply currents of 0.3mA and 25mA respectively. The programming voltage is 12.5V. This component adheres to MIL-STD-883 Class B screening standards, indicated by its screening level reference standard.
