Texas Instruments SN74ACT2159-22FN is a CMOS Cache Tag SRAM with an 8K x 9 organization, providing 73,728 bits of storage. This component features a maximum access time of 22ns and operates asynchronously. Designed with a 3-state output characteristic and an output enable function, it is housed in a 44-terminal J-Bend PQCC package (S-PQCC-J44). The device supports a supply voltage range of 4.75V to 5.25V, with a nominal 5V operation. This SRAM is suitable for applications in networking infrastructure, high-performance computing, and telecommunications systems where fast memory access for tag buffering is critical. Its parallel interface and surface-mount capability facilitate integration into complex board designs.
