The Texas Instruments SN74ACT2157FNR is a Cache Tag SRAM with a 2k x 16 memory organization, providing a total density of 32 kilobits. This CMOS component features an asynchronous operating mode and a maximum access time of 20 nanoseconds. The SN74ACT2157 series device operates with a nominal supply voltage of 5V, ranging from 4.75V to 5.25V. It is housed in a 44-terminal PQCC (Plastic Quad Flat Pack) package with J-bend terminals, suitable for surface-mount applications. This component is designed for use in systems requiring high-speed memory lookup, commonly found in computing and networking infrastructure. The output characteristics are 3-state, and it offers a parallel interface.
