The Texas Instruments 54AS870 is a 20ns, 2-port, 16x4 Multi-Port SRAM with a TTL interface. This asynchronous device, organized as 64 bits, features a dual memory architecture suitable for multibyte operations. It operates within a temperature range of -55°C to 125°C and requires a supply voltage between 4.5V and 5.5V. The SN54AS870JT is housed in a 24-pin Ceramic Dual In-line Package (CDIP) with through-hole mounting. Its 3-state outputs enable flexible bus interfacing. This component is commonly found in applications requiring high-speed data buffering and inter-processor communication within telecommunications, defense, and industrial control systems.
