The Texas Instruments SN74AS870NT is a 16 x 4 Multi-Port SRAM with a maximum access time of 15ns. This asynchronous memory component features dual ports and is designed for multibyte architectures, offering two independent access paths to the 64-bit memory array. The 74AS870 series device utilizes TTL technology and provides 3-state outputs. It is housed in a 24-pin PDIP (Plastic Dual In-line Package) with through-hole mounting. This component is suitable for applications requiring simultaneous read and write operations or concurrent access from multiple processors or bus masters, commonly found in high-performance data acquisition systems and communication infrastructure. The operating temperature range is from 0°C to 70°C, with a nominal supply voltage of 5V.
