Key Features
- Gated Serial Inputs: The SN74LS164N has gated serial inputs (A and B) that allow complete control over incoming data. A low at either input inhibits entry of new data and resets the first flip-flop to the low level at the next clock pulse.
- Fully Buffered Clock and Serial Inputs: This feature ensures that the clock and serial inputs are fully buffered, enhancing signal integrity.
- Asynchronous Clear: The component includes an asynchronous clear function, allowing immediate reset of the shift register regardless of the clock state.
- Low Power Consumption: Part of the 74LS series, this component is known for its low power consumption.
- High Noise Immunity: The SN74LS164N has high noise immunity, making it reliable in noisy environments.
Applications
The SN74LS164N is widely used in various digital circuit applications, including:
- Serial to Parallel Data Conversion: It is used to convert serial data into parallel data, which is essential in many digital systems.
- Shift Registers: The component can be used as a shift register in digital circuits, allowing data to be shifted in and out serially.
- Digital Counters and Timers: It can be integrated into digital counters and timers due to its ability to handle serial data.
- Communication Systems: The SN74LS164N can be used in communication systems where serial data needs to be converted to parallel data for processing.
