3. Speed: The device supports high-speed operation, with a maximum clock frequency of up to 100 MHz, allowing for fast data processing and transfer.

4. Output Drive: The outputs are capable of driving standard TTL loads, providing flexibility in interfacing with other components in a circuit.

5. Logic Levels: The SN74LV164APWR is designed to work with LVTTL (Low Voltage TTL) logic levels, ensuring compatibility with other low-voltage devices.

6. Package Type: The device is available in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, which is compact and suitable for space-constrained applications.

7. Temperature Range: It operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

8. Applications: Common applications include data storage, data transfer in communication systems, LED control, and various digital signal processing tasks.

Pin Configuration:

The SN74LV164APWR features a total of 16 pins, which include:

• Data Input (DS): The serial data input pin.
• Clock (CLK): The clock input pin that controls the shifting of data.
• Output Pins (Q0 to Q7): The parallel output pins that provide the shifted data.
• Reset (CLR): An active-low reset pin that clears the register.
• VCC and GND: Power supply and ground pins.

Electrical Characteristics:

• Power Consumption: The device is designed for low power consumption, making it ideal for battery-operated devices.
• Propagation Delay: The typical propagation delay from the clock to the output is low, ensuring quick response times.

Summary:

The SN74LV164APWR from Texas Instruments is a versatile and efficient 8-bit shift register that is well-suited for a variety of digital applications.
