SN74LV165AMPWREP

The SN74LV165AMPWREP is a high-speed, low-voltage, 8-bit serial-in, parallel-out shift register from Texas Instruments. It is designed for use in various digital applications, including data storage, data transfer, and signal processing. Below is 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 serial-to-parallel data conversion.

2. Serial Input: Data is entered into the shift register serially, allowing for efficient data handling and reduced pin count in designs.

3. Parallel Output: The SN74LV165AMPWREP provides parallel output, enabling simultaneous access to all stored bits, which is useful for interfacing with microcontrollers and other digital devices.

4. Low Voltage Operation: It operates at a supply voltage range of 2.7V to 5.5V, making it compatible with low-voltage logic levels and suitable for battery-powered applications.

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

6. Shift Control: The device features a shift clock input (SRCLK) that controls the shifting of data into the register. The data is shifted on the rising edge of the clock signal.

7. Output Control: The output enable (OE) pin allows for control over the output state, enabling the user to disable the outputs when not needed, thus saving power.

8. Asynchronous Reset: The SN74LV165AMPWREP includes an asynchronous reset (SRCLR) feature that allows the user to clear all bits in the register to a known state (logic low) without needing to clock the device.

9. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

10. Package Type: The SN74LV165AMPWREP is available in a TSSOP (Thin Shrink Small Outline Package) with a 16-pin configuration, which provides a compact footprint for space-constrained designs.

Applications:

• Data Communication: Used in applications where data needs to be transmitted serially and received in parallel.
• Microcontroller Interfacing: Ideal for interfacing with microcontrollers that require additional I/O pins.
• LED Control: Commonly used in LED display applications where multiple outputs are needed.
• Signal Processing: Useful in digital signal processing applications where data needs to be shifted and manipulated.

Electrical Characteristics:

• Supply Voltage (Vcc): 2.7V to 5.5V
• Input Voltage Levels: Compatible with TTL and CMOS logic levels.
• Propagation Delay: Typically low, allowing for fast data transfer rates.

Conclusion:

The SN74LV165AMPWREP is a versatile and efficient shift register that provides a reliable solution for various digital applications requiring serial-to-parallel data conversion. Its low voltage operation, high-speed performance, and compact package make it an excellent choice for modern electronic designs.
