The Texas Instruments SN74AS871N is a 2-port, 16x4 Multi-Port Static Random-Access Memory (SRAM) from the 74AS871 series. This component offers separate I/O for each port, enabling dual memory architectures for multiprocessing and bus contention resolution. With a maximum access time of 16ns and TTL technology, it provides a 64-bit memory density. The 28-pin PDIP package features through-hole mounting and a terminal pitch of 2.54mm. This device is suitable for applications requiring high-speed data buffering and inter-processor communication, commonly found in industrial control systems and networking equipment. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage between 4.5V and 5.5V, with a nominal 5V operation. Output characteristics are 3-state.
