The TC74HC165AF(EL,F) is a type of chip that falls under the category of logic - shift registers. A shift register is a type of memory chip which stores binary information in the form of a serial data shift which moves through the register. This type of chip is particularly useful when dealing with large amounts of data as it allows for quick movement of data which also results in a reduction of chip latency.The TC74HC165AF(EL,F) is a high speed shift register, which is primarily used to read data from external sources including sensors. This chip is often used in the design of systems which require multiplexing or the conversion of parallel data into a serial form. It is also often used in automotive applications as its high speed makes it suitable for concurrent operations in a wide range of vehicles.In terms of internal architecture, the TC74HC165AF(EL,F) is composed of 8 stages of D-type flip-flop register, each of which contains an output, an input, and a shift/load pin. As the name states, the shift pin is used to shift data from one flip-flop to the next, while the load pin is used to load eight bits of data in one clock cycle. All 8 stages are connected serially, meaning that when the shift/load phase is active the data from the first stage will move to the second stage, and so on up until the 8th stage. Once the 8th stage is reached, the data will loop back around to the first stage and repeat the cycle.As previously stated, the TC74HC165AF(EL,F) is primarily used to read data from external sources and thus has two input pins; the Serial Input (SI) pin and the Load/Shift Control (LS) pin. The SI pin is used to input the data which will be shifted through the register while the LS pin is used to control the direction of the data shift. If a HIGH signal is detected on the LS pin then the data will shift to the next stage and if a LOW signal is detected then the data will remain unchanged. The LS pin can also be used to load data into the register in the same manner described above.Overall, the TC74HC165AF(EL,F) is an incredibly useful chip that can be used to efficiently transfer large amounts of data from one device to another, at high speed and with minimal latency. It is primarily used in multiplexing applications, providing an efficient and space saving means for wiring complex systems, as well as in automotive applications for maximizing data throughput in resource-limited environments.
