SN74LV165ADR

The SN74LV165ADR is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It is designed for high-speed data processing and is particularly useful in applications where data needs to be shifted in serially and then output in parallel. Here’s a detailed description of its features and specifications:

Key Features:

1. 8-Bit Shift Register: The device can store and shift 8 bits of data, making it suitable for applications that require handling multiple bits of information simultaneously.

2. Serial Input: Data is entered into the register serially, which allows for efficient use of pins and simplifies the design of circuits that require data input.

3. Parallel Output: Once the data is shifted into the register, it can be accessed in parallel, allowing for quick retrieval of all 8 bits at once.

4. Low Voltage Operation: The SN74LV165ADR operates at a low voltage range, typically from 2.7V to 5.5V, making it compatible with modern low-power digital circuits.

5. High-Speed Performance: The device supports high-speed operation, with a maximum clock frequency that allows for rapid data shifting, making it suitable for high-performance applications.

6. Asynchronous Reset: The shift register features an asynchronous reset function, which allows the user to clear the register at any time, setting all outputs to a low state.

7. Shift Control: The device includes a shift clock input that controls the timing of data shifting, allowing for precise control over the data flow.

8. Output Enable: The outputs can be disabled to reduce power consumption and prevent loading on the output lines when not in use.

9. Package Type: The SN74LV165ADR is available in a variety of package types, including the 16-pin TSSOP (Thin Shrink Small Outline Package), which is compact and suitable for space-constrained applications.

Electrical Characteristics:

• Supply Voltage (Vcc): 2.7V to 5.5V
• Input Voltage (Vin): 0V to Vcc
• Output Voltage (Vout): 0V to Vcc
