Features
1. Low Power Consumption: The LS series is designed for low power usage, making it suitable for battery-powered applications.
2. High Speed: It supports fast data transfer rates.
3. Serial Input: The data is input serially through a single pin, which simplifies design.
4. Parallel Output: The data can be accessed in parallel, enabling multiple operations simultaneously.
5. Clear Function: A direct clear input is available to reset all outputs to a low state.
6. Cascadable Design: Multiple SN74LS164DRs can be cascaded to create longer shift registers without additional control circuitry.
7. TTL Compatible: It is designed to be compatible with TTL logic levels, ensuring easy integration with other TTL circuits.
8. Wide Operating Temperature Range: It operates reliably over a wide temperature range, making it suitable for various environments.
These features make the SN74LS164DR a versatile component in digital electronics, used in data storage, transfer, and sequencing applications.
Pinout
1. VCC (Pin 14): This is the power supply pin, where a voltage of typically 5V is supplied.
2. GND (Pin 7): This is the ground pin for the IC.
3. A and B Inputs (Pins 1 and 2): These are the serial data input pins used for feeding data into the shift register.
4. QA to QH Outputs (Pins 3 to 6 and 10 to 13): These are the parallel data output pins representing the 8 bits of the shift register.
5. CLR (Clear, Pin 9): This pin is used to reset the shift register, clearing all bits to 0.
6. CLOCK (Pin 8): This pin is used to provide the clock signal, which shifts the data in the register with each clock pulse.
This IC is used for converting serial input data into parallel output, typically in digital circuits where data needs to be shifted and stored.
