The Texas Instruments SN74ACT2140AFN is a high-speed CMOS cache SRAM with an 8K x 18 memory organization. Featuring a maximum access time of 25ns, this component operates asynchronously and supports 3-state outputs with an output enable function. The device is configurable as either 2-way 4K x 18 or directly mapped 8K x 18. It is housed in a 52-terminal J-lead chip carrier (PQCC52) package, designed for surface mounting. Operating within a supply voltage range of 4.75V to 5.25V, the SN74ACT2140AFN is suitable for applications requiring fast data buffering and high-bandwidth memory access, commonly found in networking infrastructure, telecommunications, and high-performance computing systems. The operating temperature range is from 0°C to 70°C.
