Texas Instruments' 74ACT2158 series offers a high-performance Cache Tag SRAM, specifically the SN74ACT2158-22FN. This component features an 8K x 9 memory organization, providing 73,728 bits of storage. Engineered with CMOS technology, it delivers a maximum access time of 22 nanoseconds, supporting asynchronous operation. The SN74ACT2158-22FN is housed in a 44-terminal J-lead plastic chip carrier (PQCC44) package, designed for surface mounting. Its 3-state outputs with an output enable function are suitable for complex memory architectures. This device finds application in high-speed computing systems and networking infrastructure where rapid data retrieval is critical. The nominal supply voltage is 5V, with a range of 4.75V to 5.25V.
