The SNJ54HC164W is a popular integrated circuit component in the 54HC family. It is a high-speed, synchronous, 8-bit serial-in, parallel-out shift register that operates under the principle of cascading multiple components to create longer shift registers.
One of the key features of the SNJ54HC164W is its synchronous operation, meaning that the shifting and latching of data occur simultaneously based on a common clock signal. This ensures precise and coordinated data transfers, which is useful in applications where timing is critical.
Another important feature is its serial input (SI) and serial output (SO) pins, which enable the cascading of multiple SNJ54HC164W components. By connecting the serial output of one component to the serial input of the next component, it is possible to create longer shift registers with increased data storage capability.
Additionally, the SNJ54HC164W has a parallel output (Q7-Q0) that provides the capability to simultaneously output all 8 bits of data in parallel. This parallel output makes it convenient for interfacing with other devices or components in a system.
The component also includes an asynchronous master reset (MR) input, which allows for the simultaneous clearing of all the shift register stages. This reset functionality is useful when a fresh start is needed or when a specific state needs to be established.
The SNJ54HC164W operates on a wide supply voltage range, typically between 2V and 6V
