74AC373SC is a widely utilized static RAM in the integrated circuit family, which works based on the principle that static RAM is made from a number of registers. As a universal register, the 74AC373SC is widely used in various applications, including personal computers, embedded systems, data acquisition systems and product testing system. As a versatile register, the 74AC373SC is also applicable to data transfer and data bus access applications.The 74AC373SC stores the state of incoming data and performs various data processing functions. It contains advanced logic functions such as cascading, parallel access, and data/address control. Thus, the 74AC373SC is also known as a serial-access latch. Specifically, 74AC373SC latch can be divided into three sections: logic, timing and clocking.The logic section of the 74AC373SC consists of a register, a register decoding circuit and a multiplexer. The register stores the input data, the register decoding circuit decodes the input data and the multiplexer creates the correct output based on the input data. The register is constructed using two interconnected stages, and each stage stores one bit of the input data.The timing section includes an READ cycle for outputting the data and a WRITE cycle for writing the data. During the WRITE cycle, the data is loaded into the register via the register decoding circuit, while in the READ cycle, the registered data is read and output from the multiplexer.The last component of the 74AC373SC, which is the clocking component, handles the clock logic. It synchronizes the READ and WRITE operations by generating the clock signals. The clock logic includes a set of cascadable frequency dividers, a data strobe and a clock counter.In summary, the 74AC373SC is a versatile serial-access latch. It’s composed of three sections, namely the logic, timing and clocking sections. It is widely used in various applications, such as personal computers, embedded systems, data acquisition systems and product testing systems.
