The Texas Instruments 54AS870FK is a 16K x 4 multi-port Static Random Access Memory (SRAM) with a maximum access time of 20ns. This TTL-compatible component features dual memory for multibyte architecture, offering two independent ports for concurrent read and write operations. Designed for high-reliability applications, it operates across an industrial temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V. The SN54AS870FK is housed in a 28-lead Ceramic Quad Flatpack (CQFP) package, suitable for demanding environments in aerospace, defense, and industrial control systems. Its 3-state outputs provide flexible bus interfacing.
